I have an A2B metro... You should check them out.

I can't speak for reliability at the moment as I only have had it a month, however I have put 400 miles on it thus far with no problems. Had a chain snapped today but that is standard bike part and I feel it must of been faulty from manufacture. They have sent out a replacement immediatly as is all covered under warrenty.

In the mean time I just removed the snapped link.

The bike has 20 mile range going 20mph without pedalling. Although of course hills will effect it, but if your planning to pedal aswell, the hub motor and you pedalling should glide you up even the steepest of inclines... The battery in hidden inside the frame aswell which is a real bonus.

Should check them out... the company is ultramotor. Let me know what you think
