I bought this model in Aug. 2020 and have since put over 5000 Kms on it. Awesome tires even on ice. used all winter up to - 17 degrees. Although it does run up to 40 plus Km fully charged in the spring, summer & fall, in the winter I'm lucky to get 26 km on a full charge, but this is presumably normal presumably with a lithium ion battery??? , it would be nice to have an extra battery. however these cost 1200.00 plus. All in all, It is an awesome machine. I haven't tried any other electric trikes and really have no inclination to do so. Only fault-Chain coming off had to add a Mechanism to stop this. Too many pedal gears this unit would be great with only 3 pedal gears.
