Kuberg Challenger :

Chain drive rear, geared freewheeling hub on front and a throttle on each handlebar side for independent control. This would also make for great mx racing... Push into corners with rear motor and pull out with front motor. nice!

gasgas uses a petrol bike with torrot electronics crammed in, not exactly revolutionary imo.. and Yamaha is a huge company with massive R&D budget but their etrial is not yet available on market.. some 2019 electric motion models have a new motor, controller, etc.. and Electric Motion Epure prototype is said to have the power equivalent of a 300cc 2stroke according to test riders, and has a patented "electro magnetic controlled clutch" ..
(so where are the gasgas patents![]()

Didn't but it suggests that it will bounce you out of the bike pretty easy, its a crooked design for a trials bike..mxs said:Anyone has seen Kuberg Challenger in flesh? .... Or at least a video, other than the promotional one or unboxing one. Real trial riding terrain.

I would love to understand the specifics of trials bike frame geometry and how it differs from mx bike geometry. Same goes for suspension. what are common measurements and weights of trials forks? How are they setup regarding compression and rebound dampening compared to an MX bike? There are maybe 2 trials bikes in my town and one is a display at a museum. I can get close to it with a tape measure but that's about it?
Are there any good Youtube channels or websites with basic overviews of trials bikes?
