The updated version of the e-bike weighing 15-16kg (33-35lbs) with 26” wheels now includes a rear rack for loads up to 15kg (33lbs), in which there is a removable lithium-ion battery with a capacity of 10.5Ah (378Wh). I would love to receive your new comments.

I’d be nervous about how you have the bottom bracket shell mounted. The cranks might not clear the two tubes you’re using in place of a downtube, and if they do the shell is still only being supported in one direction and will be in serious danger of twisting or snapping.

Edit: additionally that seattube isn’t going to work. It’s too wide for the post, and you’d have to do some extremely uncomfortable fabricating to correct that.

Be weary of how many weld/connection points there are, especially on the rear triangle. This is a heavy bike, and fully rigid – this is a recipe for either extreme discomfort, or mechanical failure.

Also, 26in wheelset are straight up outdated and hard to find in a pinch- 650b (27.5) or 700c (28/29er) is not only far easier to find, but also allows more tire choice.

That fork looks carbon. Stick a steel one on, much stronger.
