Clean, unique design and build quality
From 3 comments
I love that you focused on commodity parts. That is excellent, I really like the placement of the system. Do you intend to take it trails riding? I would just be careful of those…
ehnto on HNThat's a beautiful piece of work, if I may make a couple of suggestions: - chamfer all exposed 90 degree angles - shrinkwrap the whole thing so it is protected from the weather…
jacquesm on HNExcellent build, also very beautiful to look at; I hope to see a video of it in action. It's strange that the author encountered difficulties in soldering XT90 connectors; I…

ehnto on HNThis is fantastic, well done! I love the simplicity of the kit. I'm extremely surprised to hear that soldering the XT90s was hard. Even a $20 Pinecil (well, maybe I shouldn't say…

Not weatherproof; exposed parts and mud/water problems
From 2 comments
Is it weather proof? I guess not since the motor windings are exposed? Where did you get the sheet metal fabricated? Otherwise looks good! When I got a 3D printer it was amazing…
2muchcoffeeman on HNCool build, but it doesn't look like it would actually stand up to the typical stresses of mountain biking (rock strikes, water, mud, debris, etc). On super smooth singletrack I…

External chain looks unsafe
From 1 comment
Nice design but that external chain looks scary.

Requests
Use a VESC controller for more control and telemetry
From 1 comment
A few ideas: * A VESC based ESC instead of the HobbyWing one will give a lot more control and telemetry, including a phone app and detailed current use logging. I know from RC…

Better connection between motor kit and frame

Questions
Maximum speed
From 1 comment
What is the max velocity? I sometimes see people on new fast e-bikes and it seems a bit scary. And sometimes the rider also looks a bit scared or not really in control.

Expected range
From 1 comment
How are the mounting brackets made (or obtained)? You said you didn’t want to CNC anything, but they look CNC or laser cut? Any estimates of your expected range?
