Bought mine in summer 2019 and have 425km on it. Very impresseed get alot of comments. I would like to see some upgrades such as a bigger or multiple front sprockets, bigger or more powerful battery or option to mount 2 batteries, a suspension system would be nice as well as a more detailed color display. It's a powerful bike know doubt but everyone eventually wants more and there's not any upgrades specifically available for this model yet that I've seen. These may seem nit picking but with these improvements the unit would be almost perfect.
