WHAT OUR CUSTOMER ARE SAYING
Comments from CYSUM's users
A bike that keeps its promises
Fast delivery, easy kit with little assembly. The bike allows you to go to 45kmh without forcing, the level of comfort is not bad at all considering the speed. The 5 modes allow you to choose a target speed for the assistance, which is very useful in town or in places where you have to drive slower. The luggage rack does me a lot of service and increases comfort. In short, I do not regret the purchase, it is the perfect tool for sunny days!
