Re: Winter quad tilter build started

I'd keep the front just wide enough to squeeze through car traffic. :wink: I guess just a tad under what an average handlebar length would be. Maybe more for sharper turns so the front tires won't hit them? Not unless your not riding with them. Then go wide!

Re: Kepler Friction drive comes of age.

Thanks for posting the distance of the bottom bracket to wheel contact. For awhile I would look at all the lightweight road bikes on Craigslist and a keen observer would notice that road bikes vary a lot in this measurement. This would leave me confused to whether your drive would work on that bike....

Re: first time buyer

At <500w power levels (some folks would say 750w :twisted: ) type of fork material is of less importance when you put torque arms on the motor. Torque arms are required on front motors (and rear motors). I wouldn't buy a complete kit from a vendor if they didn't supply one as part of the package, it...

Re: first time buyer

Not sold on a BBS2 as a die hard daily commuter vs. the (current top line & improved) BBSHD. The right side (where the front cog attaches) of the motor uses a plastic-type cover. Good for about 2-5 years, depending on riding style, before the plastic cover disintegrates, leaving the internal gears t...

Re: HopMod eBike | Frame Kit

I don't trust that adjustable BB. Doesn't look strong enough with 2 bolts and lateral pedal forces. That needs to be re-engineered.

The rest of the bike is pretty cool.

It does look too much like a moped/motorcycle if your only going to put average e-parts on it.

Get rid of rear multicogs that use thinner chains and replace with a 3 speed internal hub wheel with a strong single speed chain.

Re: Keeping Battery Pack Warm in the Field

Very few live in areas where the severe cold actually effects the ability to ride under power. You just realize that the battery will sag a little, but at anything 36v and over you won't notice a significant lack in power. If anything, calculate your trip distance you want to ride, and find a batter...

Will this used 36v (10s) w/29e cells work on an Eskate

I have a used 10s dolphin pack with 29e cells (current cell tech five years ago). Will this provide enough amps to power a 2x motored Eskateboard. I'm not sure what the C rating are for them. I think it's 6p. If not then it's 5p.

Plan is to put it in a backpack and have corded leads to the ESC. :P

Re: BBS02 - LCD is slow in registering speed

Double check your spoke magnet & magnet sensor. Make sure they both are close enough to each other. I had to glue another magnet to the existing spoke magnet making it closer to the sensor. Otherwise, I'd get an error message.
