DOUBLE Powered Surron Light Bee X // Updated Tests + Full Speed!

In this video I test the Torp TC500 in more depth and do a few tests on the bike such as a comparison to the standard power of the Surron Light Bee x.
I also do some full speed tests and wheelie tests.
I also talk about a few corrections I had to make to the calibration of the speedo and go over a few of the settings in the Torp app.

Any questions please feel free to ask in the comments below.

In my last video we installed and ran a few tests on the torp tc500 controller available for the siron lightbe but when doing the test I was still very new to how to actually tune and set up the controller correctly that then led to a few false results and a lot of questions

From people so that’s why in today’s video we’re going to go out for a ride on the siron we’re going to look a lot deeper at how the top tc500 actually changes the siron we’re also going to look at a more in-depth way of how you

Can tune the bike with the app on your phone and what settings we can use on the siron to really get it to its full potential there’s going to be a few other tests involved today like wheelie hill climbs top speed test and now we’ve actually got it set up right so without

Further Ado let’s get out on the bike and we’ll start running a few tests okay so we’re out on the bike so before we get into running the tests that I wanted to do today with the top tc500 I want to make note of a few things I actually had

To change on the app from when I set the bike up to how I’ve been riding it recently and after riding the bike getting used to it how I like my settings to be set at so for a start when I first did the tests on the tc500

In the installation video I had my sprocket size and my wheel size set wrong now the problem with this is you need your sprocket ratio size your gearing ratio and you need your wheel size to be set correctly for the bike to know how fast you’re actually going for

The speedo to be calibrated therefore the top speeds were wrong the mileage counter was also wrong the odometer that was also thrown out a false reading how many miles I’d done again because the skar ratio and the sprocket size that was all set wrong and the wheel diameter

Was set wrong so for the wheel diameter size to be set it’s the exterior measurements of your wheels so that is rims plus tires for the gear ratio to be set right you have to have what size sprocket you’re using set right so I don’t use the stock 48 too sprocket

Anymore I’m using a 56 Toth sprocket therefore I had to set the sprocket ratio size on the app to 56 to so we’re at the first location where I wanted to run a few of these tests which will be comparing the stock power of the seron

Compared to the top power of the tc500 that we can be running which is 8.6 Kow so at this spot with this track behind me we’re at a slight uphill and then it comes into a bit of a hill climb a bit further back I’m going to be doing a few

Runs in the stock power form which is roughly 4.5 KW then we’re going to be doing a few runs at top power that you can set on the tc500 then we’re going to be comparing the two so you get a real idea of what the torp is capable of

Turning the sir on into so first of all we’re going to take a look at the stock power before we start I’m going to take a quick look at the app so you can see what I’m actually running the bike at so we got motor current at 450 amps from

What I understand motor current is how much torque how much power the motor is going to have changing the battery current is going to be the thing that changes the maximum power of the bike so at the minute when we go back down to 73

Amps that’s what puts us at 4 .5 KW then for RPM we’ve got infinite because we don’t want to limit the speed throttle release regen break lever regen both on zero then field weakening we’ve got set to 30 amps field weakening is going to be the thing that’s going to change the

Top speed so we will have a look at changing that later on in the video but for now we’re going to leave that at 30 amps okay so we’re set in eco mode which is what we had the bike set at for all those settings that I just showed you

We’re going to hit the go button and we’re going to have a quick go up this track see what we can do so the wheel does still spin this should be exactly like sport mode was on the original siron setup the original s on tune it definitely feels like stock was climbs it

Easily still get a little bit of air off of the jump and it pulls no problem up the hills so again coming downhill feels exactly like stock would have felt still get those speeds up there we’re doing 45 mile an hour so if you’ve got a sir on you know

Exactly what sport mode feels like that is exactly what sport mode would do you still got the torque in there to throw the wheel up if you want but then you’ve also got power to get some good speeds so going back to the app to look at the settings that

We’re using for sport mode we’re at estimated power 8.6 KW motor current is set to 500 amps battery current is set to 140 amps RPM is at infinite regen completely off again and field weaken in is at 30 amps so this is nearly everything maxed out powerwise the only

Thing we can actually turn up now is the field weakening but there is warnings to do with the field weakening when you go too high so again we’re going to keep it at the lower ampage at the minute shouldn’t really make massive difference to the top speed being that low but even

Where we’re riding the top speed is a bit Irrelevant this is for more off-road testing so that is all the settings we got the bike out in sport mode literally everything maxed out apart from field weakening so we’re back down the bottom we’re going to press the M button bike

Is now in sport mode so we’re now at the full potential of the siron with the top tc500 let’s hit it full throttle so ready the back wheel spinning like crazy pull straight up here absolutely no problems loads of air off the little jump and it just wants to keep going so

Hopefully there you would have noticed how much more power the siron is pulling even just from here in the bike and how the bike wants to throw that power out so hope hope you can see from those tests there a bit of the difference between the stock sport power mode and

The 8.6 KW mode hopefully you saw that there’s a hell of a lot more power being thrown out making the bike accelerate a lot quicker not necessarily making the top speed quicker but the acceleration is absolute Insanity so I’m in stock sport mode form still on the S on holding the wheelies

Uphill so while we continue on on sort of the main route that I usually do on my S on wanted to talk about a few more things on the top few few sort of changes compared to the stock bike everything that I talk about really is

Going to be compared to the stocks are on controller I’ve never tried any other controller I’ve only ever tried the stock siron controller and the toor tc500 and one of the biggest questions that you’re probably going to get is the range how much does doubling the power

Of the bike affect the range and from what I’ve played with so far if you have the bike in the full power mode of 8.6 KW it does obviously drain the battery a bit quicker depending on how you’re using that battery as well so if I was

Riding the bike with a stock controller in sport mode I would roughly get around 25 M to a ride and that wasn’t necessarily draining the battery I always like to get home with a good 20% minimum in the battery just so I know that I’m not draining the battery too

Much when running the same tests on this bike again standard riding not pushing the bike I would be pushing around about the same mileage even with the bike at 8.6 KW so even though I’m not mashing the throttle and getting full speed runs out of it I am getting more power from

The throttle because it’s a lot more sensitive it’s got more Instant Power rather than having to twist the throttle the full way to get the 4.5 Kow You’ get stock and then not only that it’s not like you have to be running your bike at full power all the time so with the

Settings that I’ve shown you in the app you can obviously have your eco mode and your sport mode set a completely different thing you can tune the controller to have a lot less power for your eco mode so if you do want to try

And save a bit of battery you do want to make your ride last as long as it possibly can you can set that AO mode to a lot less power less motor current less battery power obviously therefore saving the power of your bike and then obviously it depends on how and where

You’re riding they will play Massive Parts in your actual range in the future I will be doing a full-on range test with the torp tc500 uh we’re going to be doing tests with the bike on a lower power first going from 100% battery down to about 20% battery and then hopefully in the

Same video we’ll be doing a full powered TP tc500 range test so the bike at 8.6 KW uh it won’t be fullon throttle everywhere won’t be flat out riding it’ll be riding like I’m doing now but just with the bike set at a lot more power then we’ll do a comparison with

The bike set at stock mode and with the bike set in full power mode so we can really see what goes on with the range something else I never actually touched on in the video where I installed the top tc500 was how much it all costs how

Much would you pay for the controller and the display screen that they sent me how much would that cost well for a start because tops out in Croatia they charge in Euros uh when you go on the website everything comes up priced in euros the controller itself is priced at

€800 and then the display is priced at €100 so add the two together you’ve got €900 that then converted into pound you’re looking at roughly 770 I think I would have to go on a converter and properly check what the conversion would be in dollars I think

That actually goes up a bit I think it is more around the $800 $850 Mark um don’t quote me on that I could be completely wrong again I’d have to check on a converter but I think roughly that’s what the conversion would be so the next part of the tests that I wanted

To do while we’re on this stretch of private road I’m just going to say that loud and clear for all the haters that want to go down in the comments private road okay so the next tests that I want to hit are going to be some wheelies so

We’re going to go back into the ECO mode setting stock sport mode setting we’re actually going to wait for this car to come past us this is what it’s going to be like to wheelie a stock sport mode siron so the there’s going to be a lot

Of compression on the forks to actually get the wheel up the acceleration coming up is going to be slow but like you can see it does do it and then once you’re up at the balance point the bike does actually hold itself really well you do

Have to use that throttle quite a bit to get back up to the balance point and once you’re at a certain speed it’s really hard to get that wheel back up once you’re at a bit of a higher speed but it does wheel a treat I feel like

The stock throttle tune which I’m going to get into throttle Tunes after this segment the one thing sir I’m definitely did get right was the throttle tune or maybe I’m just so used to it that that’s the only one that I care for but stock mode wheelies they do happen it’s a bit

Slower the wheel does come up and then you need a lot more throttle to actually get the wheel keep bouncing up but like you’ve seen a probably a million times before it wheelies so then going into sport mode so we’re in the full power mode now we are slightly uphill I don’t

Need to compress the forks whatsoever I just hit the throttle and the wheel comes up that is not me trying at all and then obviously because you’ve got so much more power available to you you have to be so much more careful on the throttle you can’t just go ripping it

Full power to get your wheel back up because you will Loop the bike in the 8.6 KW mode literally throttle and the wheel comes up and it comes up quick uh so like I say after this we’re going to be looking at the throttle settings I’ve

Got tuned at but it wheelies like an absolute beast and you’ve got disposable power there to throw the bike around even when you get up to say 20 mph the wheel will still come up you will have to put a bit of effort into getting the

Wheel up at 20 mph but the stocks are on for me was a massive struggle to wheelie if you were doing anything above 10 15 mph let’s get to 20 mph so we’re at 20 bit of a pull-up and that wheel still comes up so easily and then if you’re really trying

You can get the wheel still keep it up uh I’m about 35 mph getting up to near 40 and near 4 40 mph is where the wheel wanted to drop and come back down which really you’re near the top speed of the bike at that you’re 10 m an hourish away

From the top speed of what stock are on would be so to lose power there really isn’t anything to sort of worry about it’s not something you can complain about losing losing really power at 40 mph the bike is already working hard for you at that point but hopefully you can see I’ve

Progressed at my wheelies quite a bit and this controller definitely helps with that I’m not saying you need this controller to wheel well because even if I go back to eco mode I can still get the wheel up absolutely fine I can even hold it there for as long as I

Want even in stock mode the bike does wheelie and the stock tune is the perfect tune to actually learn wheelies you’re not going to have too much power you’re not going to have not enough power it’s the perfect learning point to actually get the wheel up once you’re a

Bit better at wheelies and you want to be hitting them faster and harder that’s when you’re going to need the more power to really use the power in different places so we’re even going to hit a knee knock knees on the seat wheel comes up this is in stock power mode again as

Well we still not in sport mode and to be honest I actually find wheelies like this a lot easier than I do sat down for some reason the balance point is just so much easier to find when you’re on your knee on the seat you can really feel when the bike’s going to

Go back you can feel when you need to bring the bike down but yeah wheelies absolutely completed absolutely insane on the uh on the power modes both power modes the way the Tor tc500 can be set up to really customize what power levels you want especially for things like

Wheelies is absolutely on point so going back to the app this is where I want to talk about the throttle settings also known as the throttle tune so on the app you have got at the top a smooth and aggressive rating mine is currently set all the way at aggressive you got the

Throttle curve so I’ve got mine atus 25% at the minute but I can change that right to 100% so for a start it’s going to be throwing out loads of power and then it will start to curve off with the more throttle you give it and the vice

Versa for if you go to minus 100% further down the throttle when you’re giving it more throttle that’s when the more power will come for a start there won’t be much power the reason I keep mine at minus 25 on the throttle curve is this is the closest to the stock

Throttle that I could get it I was so used to the stock throttle and really happy with how the stock throttle performed I really didn’t want to change it and when I started messing around with the throttle curve on this app all I really wanted to do was get back to

How the throttle originally felt I didn’t want a different throttle feeling I just got really good at controlling the throttle with how it was set up so that’s exactly what I wanted which is how we’ve got it set here minus 25% on the throttle curve fully aggressive this

Is exactly how the stock throttle felt to me they moving further down we’ve got dead zone at 1% I think the break lever and the thumb response I think that’s something to do with the regen throttle so I don’t think that’s anything to do with your actual throttle and the dead

Zone I believe is how much you can turn the throttle before it will kick in so with mindset at 1% it kicks in fairly early as soon as you’re hitting the throttle it kicks in the highest you can go is up to 7 % so you can give it 7% of

Your throttle twist before the bike starts moving I think that’s what it means don’t hold me to it but I’m pretty sure that’s what dead zone means if anyone’s clued up on the dead zone and wants to educate me down below in the comments if I feel free but for now

That’s what I’m going to say the dead zone is at least that’s what it feels like so we’re now at another stretch of private road which is where I wanted to do the speed tests so for a start we’re going to be going in eco mode which

Again is set to the same as the stock sport mode setting on the siron the one thing we are going to change to these settings is we’re going to put field weakening up to 50 amps so we’ put field weakening up to 50 amps we’re still running 450 amps on the motor current

Still at 73 amps on the battery current still at estimated power of 4.5 KW I’ve also got my GPS set up so I’m going to put this in between my legs and we’re going to get a read in on the GPS compared to the speedo on the bike we’re

Going to do a full speed test at the power of a stock are running sport mode then we’re going to come back and we’re going to do the same again for the full power mode seeing if we get any sort of increase remember we are at 50 amps of

Field weaken and this is not the highest if we set it up higher we would probably get an increased top speed but then we’re also risking damaging the motor by doing so and we’re going to get going and with Full Throttle we are going to be going slightly uphill and slightly downhill in

Places so we’re at 32 we’re at 40 41 42 43 44 up to 45 46 47 looks like we’re going to stick around we’re gone back down to 43 so I think that’s what we’re going to get so we got 47 mph on the speedo on the

Handlebars if we go down and look at the GPS Speedo the maximum speed was 45 mph so I’m going to go ahead and I’m going to stop the GPS Speedo so we’re going to go back to where we were we’re going to do the exact same thing on the full power

Mode again this isn’t full battery a full battery might give you a bit more of a result bit of a higher top speed I purposely wanted to do this around this battery percentage because once your battery does come down from the 100 to 90% Mark obviously you’re going to lose

A slight bit of power so this is going to give you a true reading of what you would probably get when riding the siron after a couple of miles of riding so we’re back at the same spot we’re going to go over to the sport mode again looking at the tune everything’s the

Same field weakening is still at 50 amps 500 amps on the motor current 140 on the battery current infinite RPM so we can go up as high as we like and 50 amps on the field weaken him so Speedo is ready to go double check and then Full

Throttle so already the speedo is saying 40 mph 41 45 46 47 48 49 50 I think the highest we’re going to get is 50 not kill the squirrel okay we’re about at the same point that we started to slow down before we got 50 mph on the display on

The bike and we got 48 mph on the speedo on the GPS so just from those speed tests you will be able to see that with the field weakening especially you can get a slightly higher top speed out of the siron it’s also worth remembering

That I have a 56 to sprocket so my top is going to be slightly less than what it would be if I was using a smaller sprocket if you are using the stock sprocket on the bike I would probably presume that you’d get an extra maybe

Five 5 to 10 mph more than what I was getting but we did have a slightly increased top speed in the full power mode of the bike slightly less top speed on the sport mode again this is still just a stock battery and you’re still getting a massive increase in top speed

Hopefully that should answer some of the questions that people had from my last video on what why the top speed was less or them saying Oh my stock sir on can get 47 mph but on your siron you’re actually only getting 40 that is because

I had the gear ratio set up wrong I had the wheel diameter set up wrong that changed everything on the speedo like I say it was telling me a lower top speed it was changing how many miles that I’d actually done on the bike so I was

Trying to do range tests it said I’d done about 8 Miles when I’d probably actually done 13 or 14 so nothing was actually tuned up and calibrated right so I was getting false readings all over the shop so with it getting done on the siron now I’m going to go ahead and end

The video here before the camera quality looks too rubbish to even carry on so hopefully this has answered a few questions that you may have had on the Tor tc500 hopefully it’s touched on a few of the topics that people wanted to conclude from my last video hopefully if

You’re looking at buying the top tc500 it’s showing you what this bike is really capable of and what it can do after upgrading well worth the money well worth upgrading it literally leaves me speechless riding the bike every single time you get used to the power

But you never get bored of the power if you do have any further questions on anything to do with the bike or the controller feel free to go ahead and leave it in the comments down below if you want to see more tests on the tc500

More tests on the siron go ahead and hit that subscribe button you won’t be disappointed there’s plenty more to come in the future I got loads more videos planned and they’re only getting better and better and better each time so with all that said and done I’ve been my
