It seems that despite Halfords and SRSuntour’s best efforts owners are still suffering power cuts from this otherwise excellent bike. I have a fix for this, sadly it’s not permanent but it will reduce the cut out to a minor inconvenience.
On the rear of the bike (left hand side, by the rear wheel) there is a neoprene patch held in place with velcro, remove this patch to show a large barrel connector, this is the power supply to the motor on the rear wheel, disconnect and reconnect the barrel and reattach the neoprene. All done it takes less than a minute.
That’s it, it really is that simple, I do this and I’m good for another 50-75 miles before I get another power cut. Or you could do this before you set off and hopefully prevent a power cut.
Let me know if this works for you or if it’s still frustrating you, or if you’ve cured the problem completely let us all know how you did it.
