1. I did order the Z20 MAX but I received the Z20 PLUS :-)
2. I am very content with this bike, value for money
3. minor issue, the left pedal makes terrible noise, I replaced the original plastic ones with metal ones
4. I find the brakes are not sufficient, I replaced the original mechanical brakes by hydraulic (shimano) brakes
5. I'm still designing a stand, so when folded, the bike does not rest on the plastic protection of the front gear.
6. the tranmission ratio could be higher, in highest gear @25km/h you have to pedal quite fast (with verry little force)
All in all I'm happy with this bike. Done only 50km, so it still has to proof its reliability.
