Interesting Paul…but was it not good uphill? Nothing for “light” offroad maybe, just for asphalt road?…nice to see your face..young man..

daytriker says:

What would you recommend for short city hops: bicycle or scooter?

dannique XXII says:

Hi, thanks for great review! On which speed is turning off the engine assistance? I saw on your video tahat you are going 27 kph and I still heared the motor assistance. Do you use original firmware?

Steve Cenci says:

I have their M365 electric scooter and it’s fantastic. This bike looks as well engineered and perfect for the city. Good review.

Юра Мочернюк says:

Very good and detailed review that covers all necessary information.

vitalkhlebnikov says:

the new price of $804.99 is unjustified (it’s selling in China for $450). It’s too expensive now and there are better options locally in EU..

Ramil Enriquez says:

hi Paul, am just curious on the drivetrain. What is the brand made of it? Shimano? Is it only a 3-speed gear? How is it compared with conventional 7-speed drivetrain? Did it satisfy or cover all speed configuration?

hoping to get one.

Thanks for sharing.
