Wisper 905T Crossbar

Wisper 705T is a modern designed crossbar bike with a good quality specification.

From £1,649.00


This bike is now out of stock at Wisper.  Due to the EU tax on e-bikes imported from China, the next 905T models will be produced in Taiwan. The colour and specification will be slightly different,   In the interim, we have in stock Wisper 905SE with additional suspension forks.  Price from £1349 with 10Ah battery.  The new 905T is expected late May and will be priced from £1699.00

This generation of Wisper bikes is now entering its third year after a very successful launch at the end of 2015. The Wisper 905T Crossbar has a 905 frame, which provides a comfortable ride, and the motor has proved to be virtually silent. During the year the logo has been “cleaned up”, and the torque sensor and controls modified.


Now the rider has power settings 1 – 4 and “F“. “F” is best described as being for Fast on the Flat!  It switches off the torque sensor and changes it to a rotation sensor giving maximum speed. However, when you come to a hill the rider needs to select 1 – 4 to benefit from the power of the bike.


The latest high efficiency 250W brushless motor in the rear hub is operated through a new style torque sensor. The 375Wh, 575Wh and 700Wh batteries are the same physical size so they are interchangeable on the bikes. Finished in Graphite Silk paint – oven hardened and matching painted alloy, full chain guard and black polycarbonate “shatterproof” mudguards, to give the bike has a thoroughly modern appearance.


A quick look down the specification demonstrates the quality of these bikes – Hydraulic disc brakes, hydraulic lockout forks, Shimano Acera 8 Speed derailleur and selector are a few of the more important details. As you would expect from a Wisper, the bikes are almost silent and the bikes are ergonomically comfortable. The two bikes share the same specification.
