  • The bikes in the SE range utilise a market leading cadence sensor that provides responsive application of power on hills through the use of 12 magnets (compared to the industry standard of 6). Cadence sensors switch the power on when pedals are turned forward and off when pedaling stops.

    As with the Torque range, the SE comes with 5 levels of power assistance enabling riders to increase or decrease assistance, depending on the incline of the road or weight of the load on the bike.

    All Wisper bikes are fitted with a twist throttle that is limited to 4mph walk assist mode whilst the bike is not being pedaled. However, as soon as you start to turn the pedals forward the throttle becomes active, by twisting the throttle you can achieve up to 15.5mph without the need to increase your pedaling effort.

    The Wisper high efficiency 250w high torque brushless motor is smooth, quiet and works in harmony with the cadence sensor to deliver a responsive, natural riding experience.

    This is the 2018 Wisper 905 SE Crossbar with a rigid fork and a 375Wh battery.

    Wisper Buyer's Guide - by John our E Bike Expert


    Wisper are a British company based down in that Kent who have been at the forefront of the e-bike scene for the last 12 years.  What we like about them is they have a very simple range of cost-effective bikes.  They essentially do two specs, SE and Torque which retail at £1099 and £1599 respectively and three frame versions in each spec - traditional “gents” style, step-through and folding all of which are the same price.


    Sizes are simple - one size fits most, with all models coming with quite a bit of adjustability for fine-tuning and you can have any colour you like so long as it’s black… red or blue.


    It was a tricky decision choosing whether or not to go for something in this £1100 price range for the e-bikes.  Some we’ve looked at didn’t quite make the grade and for a while it looked like the overall quality was too heavily compromised to keep the price down however Wisper’s decision to keep things simple means they’ve managed to fit in Tektro disc brakes, Shimano gears, Kenda puncture resistant tires, racks, lights, kickstands etc etc.  Additionally the build quality of the frame belies the price and they back this up with a 10 year, transferable warranty.  A 10 year warranty is much longer than the average in the bike business already but transferable warranties are very rare so Wisper are obviously feeling pretty confident...


    Since taking Wisper into stock they’ve been very well received and one thing which has been popular has been the “throttle” controller.  The left grip has a throttle system which takes the bike to approx 4mph.  If you pedal at all, even just lightly, whilst the throttle is open then regardless of what mode the bike is in then it will max out the electrical assist to 15.5mph - ideal for steep hill starts!


    So that’s Wisper then, the newest brand in the Biketreks stable.  Give us a shout if you’ve got any questions we’ve not covered or just call in, see them for yourself and maybe take one for a quick spin!
