Front kit is awesome
Really good, I recommend to use an handlebar remote. Front motor is better cause it doesn't interact directly with the transmission so you can go hard and add a lot of manual acceleration if you want that. edit : i have a problem with the kit everything working perfectly but just sometimes randomly or at specific location the kit wait to go under 20km/h to be able to kick back again and then work again perfectly as it supposed to do. I think it only happens in certain areas where the transition between downhill and uphill isn't sharp enough.
