Additional Features

Regen momentary button
Rear disc mounted brake (rarely used, 90% of the time I just coast
and use regen. The front and rear brakes are safety back-up for hard
braking events)

This was originally an electric motorcycle with a chain drive, but I
purchased it as a rolling chassis and mounted a rear hub motor and
sourced new power components.

The BMS will occasionally cut power at highway speeds with a sudden
change in headwind, and after ~20 seconds at high speeds up a hill.
I plan to upgrade to a 150A/200A BMS to avoid this.

I commute 12 miles to and from work with this and it works well. It
is 8 city and 4 highway miles. I typically arrive at work with 60%
charge. With the on-board charger, I gain all that back in 60-90
minutes and I've never had an issue with range. There is easily space
to add more batteries if need be in the future.
