ASA SPEED Y25.01 - Digital Tuning Module for all Yamaha eBikes with PW-D engine limited to 25km/h originally

If you are a potential buyer from the UK please be aware of the following. There is no indication in the sales information or installation guide (which is very limited) that the module will not work in MPH format. This has caused me immense stress and time, as I am a competent mechanic and after fitting the module as per instructions it failed to work, in fact, the bike was worse than it was before! After numerous emails back and forth with the supplier they then informed me that the unit must be in KM during installation and for further use, there fore rendering the MPH format useless which is vital in the UK. Having the bike up and running we took it for a ride (my wife riding the e bike who's bike it is) and after only 1 km the power assist failed and we had error flashing on the display screen! Nothing would clear the screen, but after a further 100 yards it returned to normal. After our ride I checked the ride stats, there was zero average speed and only 5.6 Kms max speed. Both obviously wrong. I am so disillusioned with this product, I have contacted the supplier with the view to returning it. The module was fitted correctly but has caused nothing but problems and stress. Colin Kermode
