    Ongoing reliability of Kalkhoff/Focus Impulse 2 motors

    Dug up this old image. It was a limited edition of 100 bikes. We built it in celebration of the Electric Bike World Tour when a Wisper was ridden through China, Japan, Australia, Vietnam, India etc. Happy days!

    Ongoing reliability of Kalkhoff/Focus Impulse 2 motors

    Thanks Crockers! Yes our throttle works to 15.5mph as long as the pedals are turning. Alistair from Atmosphere in Bristol sent me an image of this 905xc Tourer our carbon matrix bike sold in 2010. Still perfect with the original battery after 6 years. Just goes to show paying a little bit more...

    Brand new to ebiking, advice please

    On the Wisper Torque, there is an F setting which turns off the torque sensor and relies on cadence sensor alone. Use the torque setting to get going then change to F setting, or simply twist the throttle, this will also bypass the torque settings. All the best, David

    Which e-bike that accelerates fast

    Of course strictly speaking the throttle should not be used, when a rider is sitting on the bike. Legally it is simply a walk along mode. It very much depends on the torque a motor produces. We have had to program in a soft start, due to the power spinning wheels when the power kicks in. This...

    Bafang Max Drive bikes

    If you are still undecided, have a look at a bike with the MTB 8000 Shimano motor, in my opinion the best of the bunch, even better than the Bosch CX. All the best, David

    Which e-bike that accelerates fast

    Most bikes will accelerate quickly if set to do so. The problem is that this can cause wheel spin in the wet or on gravel. Most businesses will program their motors to "soft start" for this reason. If you need a bike without soft start, don't go for the more sophisticated products, if you do...

    Bafang Max Drive bikes

    Good point Darryl, The value of buying a bike from a local dealer is huge, even £150.00 in my opinion is money well spent. All the best, David

    Bafang Max Drive bikes

    FreeGo are excellent when it comes to Warranty work, I was a Director with them for nearly two years, both FreeGo and Wisper have the same ethics when it comes to service and support. All the best, David

    Bafang Max Drive bikes

    I think this is the same Chinese battery and down tube used by Oxygen, Axis, Juicy Bike etc etc. You should have no trouble sourcing them in the UK. All the best, David

    Has anyone tried to register an S-class in the UK?

    Hi Craigor, I'll call one off the guys who registered one to find out next who insured his bike, but several HS bikes have certainly been registered. Sorry not to have picked up on this earlier, we are absolutely flat out at the moment. Not much time to post on Pedelecs I'm afraid. All the...

    Wisper bike problem with pedelec

    hammer ebikes?

    Don't forget public areas include anywhere the public have access. Such as private fields or land with public footpaths or bridal ways. Riding one of these bikes is the same as riding an unlicensed motorbike without tax, insurance, MOT etc. Be careful. All the best, David

    Use Freego on throttle only?

    Hi Alan, in Dave's absence, I'll have a go at explaining. The 4mph or "walk along" control is allowed by European regulations to assist pushing the bike when walking along side. Strictly speaking it should not be used to power the bike when a rider is on the bike, however that would be hard to...

    Refurbish Freego Eagle

    I agree, when used in conjunction with a good sinewave controller and decent softwear, not only is this motor practicaly silent it's Torque is phenomenal.
