It should be possibility to add electric support at all travel time to increase traveling velocity for example based on constant power.
The bad thing about the Bike was that i didnt receive fenders for the tire and i didnt even recieve a backlight. But otherwise i like the bike so i will give it 3 starts
Bought the M1, arrived within a week and put together within 10 minutes. Works really well, we bought two and my friend also bought one. Very pleased with the bikes 👍🏼
