Hi folks just adding some background as I've been using a 29 MTB with 36v Yose kit (upgraded to KT) for a couple of years now and like it a lot
It's on semi slick tyres from Curio, rear motor is from a 26" wheel - relaced into a 29" rim, original Yose conroller has been upgraded to KT (I'd say this is an essential mod for Yose kit!).
Most routes are B roads or gravel tracks which it suits well, steering is good but I guess the larger wheels would be slower on the turns than 26" for any serious MTB routes.
I'm over 6ft so the XXL frame and 29 wheels are a better size for me, ride is smoother, torque from the motor is reduced due to the larger rims but it still runs happily at a decent speed.
I's a shame EVERY route from my house has at least a couple of short steep climbs where the motor bogs down badly - not enough to stall it but it's obviously running well below it's "happy" speed.
The first layout was with the battery on the rear rack, handling was fine but it was very tail heavy with the battery and motor all at the back wheel, the battery is now mounted on the frame and the bike feels a lot more balanced when you lift it.
Possible (but low priority) upgrades for the future involve moving to 48V and looking for a motor with more torque, ideally also wound for higher speeds..
Yose 350 rear hub kit - transplanted onto Scott !
Time for a new project, the main bits are a rather nice Scott 29er (immaculate!) + Yose/Lishui 350w 26” rear wheel kit + random KT parts collected from various places. Remove the 29er wheels, fit the Yose 26" rear wheel & matching front wheel, modify 180mm caliper to fit the 160mm disk. Let the...
