VOLspeed V3 - Yamaha PW-X / PW-X2 / PW-SE / PW-ST / PW-TE / PW-CE / Air Drive

This unit is fantastic! Thanks for the great service. This has transformed my Haibike into a much more pleasurable experience. No more bogging down after 25K I love it.

Excellent product and service. Very quick to reply to messages and queries. I would highly recommend them and I would not hesitate to use them in the future.

Overall very good but one small thing when you set the speed to 28mph onthe display the bike will only get to 21mph is there something else i have to do to get max speed. Apart from that very good.
