Message me mate I'll get you doing 30mph mine dose 33mph and just the gears what restrict me now, these bikes defo not tamper proof nothing is, your prob see messages now saying if it dose thos speed your blow the motor up or it will cut out and go in low speed mode and you get 3 strikes to unlock it back to 15 mph this is all untrue I have easy done over 100 miles and can go 30 miles non stop at 30mph with no problems. Your lose 5 to 10 miles distance on the battery apart from that I would defo recommend my wayfarer rides a dream now I can do 10 miles in 45 mins. Any way message me if you want to know how it's done takes 3 mins to do it's free to do and you can restrict it again and no one would know it's ever been de restricted !
Hi Jazzmann007, my own mathematical ability is far from good, but I think that completing 10 miles in 45 minutes equates to an average speed of 13.33 miles an hour.
I used a 2015 crankdrive Haibike Yamaha to commute to work and back, cross country to work with no need for speed, but lots of fun, and on the road on the way back home where I did want to go faster to get home quicker when I was tired late at night after my shift. My bike could assist me above 15.5 and I aimed to complete my 10 mile journey home at an average speed of 20mph and take 30 minutes for the journey. This it could do fully laden with a heavy man and two full panniers on a B road route with a few hills.
I did not use full assist on my homeward journey, only the lowest eco, and the middle standard of the three I had. I also switched the assist off on the steep downhill parts of the route. I put in plenty of effort myself to get a good work out. I used no more than half the capacity of my 400Wh battery to get home throughout the year, less in the summer and closer to half used in winter. My original battery is now in its eighth year and still working well.
I have now retired and lowered the bikes gearing for its new life spent mostly off road climbing occasionally steeper and technical challenging hills, which means it cannot go as fast on the road. But I don't need to any more.
My well used bike has now completed 16,078 miles.
