29 genesis setup

[BionicOnion]

Hi, this is my new, less janky, rebuild. Swapped my 1kw hub motor from Amazon the wife got me a few years ago. So really its a mullet build. Still needs a few touchups.


48v 13s 15ah engwe battery
Orange fardriver clone controller
Removed rear rim brakes due to different wheel
Shunt needs installed to verify power draw

First rode yesterday and its MUCH more fun on this bike. Im attributing it to the controller honestly but it definitely has better acceleration and top speed.

Controller and wiring in left rear box, right rear box currently just holding the charger and other little things. Like building the new torque arm/rear brake bracket/trailer mount. Rounding edges and painting added parts etc. And definitely going to be changing out that seat

Considering shifting a few parts around when touching up but here's my choices on power
1. Keep it the way it is
2. Install boost converter and I can ramp the voltage up with the same battery for higher top speed at the cost of range
3. Make and install alternate battery I have which would make it either 15s or 17s depending on me. 27ah with over 100amp draw possible which is more than the controller pulls. The negative here is no bms, and would use the boost circuit to charge to say 4.05/cell.

Any critiques welcomes or questions

Lookin good The diy battery might provide an opportunity to lower the battery and the whole bike centre of gravity which should give you a much better experience on and off rd. a 100a bms would be a little extra expense but well worth it if investing that much in cells to start with.

Seems like a lot of weight cantilevered out on a seat post mounted rear rack.

Yep, that big battery needs to be in the triangle and looks like with some work, could fit by using a triple bob.

Thanks guys, yea the battery's i dunno....14 lbs or something. Maybe I'm off, unfortunately it won't clear the center triangle and the frames aluminum, which i don't particularly trust self tappers to hold the weight of the battery that low. Yeah it would absolutely be better for bike balance

figured id update with my torque arm/brake caliper mount/trailer mount progress. All tacked in, ready to finish weld and paint when I put the new tire on. Removal is easy with just removing caliper and then it comes off like a normal torque arm. I havent welded in a few years so some of these don't look as nice as id like but they work
