Yamaha battery not reaching expected range?

[Oski1997]

Oski: Battery range depends on so many factors we simply cannot say "that doesn't sound right". The major difference is the rider him/herself. My max range on a 500 Wh battery with Yamaha PW-X2 ridden in two low assist modes was some 40 miles; you can ride for 57 miles at the conditions you describe. My brother could ride for 75 miles and still was left with 23% battery. It is all down to the rider's leg input.

Thanks Stefan. Yamahonian, are you still just getting 28 miles out of your battery?
