Make light work of mountains with the Twitter VS7.0ER1 Electric Mountain Bike. If you’re looking for effortless electric riding, on and off road, the VS7.0ER1 is an outstanding option.

The 10ah battery will give you up to 40 miles of electric pedal power – perfect to get you over those peaks. And when you’re back after riding, a charge time of 4-6 hours means the VS7.0ER1 will be ready to go again in no time. Power is delivered by a rear hub motor with torque sensor, for smooth and responsive assistance when you need it, the VS7.0ER100 comes with an integrated smart control system that protects the battery from overheating, short circuiting or overcharging.

The electric motor of the VS7.0ER1 is controlled via full LCD Smart Head Unit. It allows you to choose from one of 5 assistance modes, depending on the level of support you require. The unit also allows the user to view additional data such as Speed , Mileage , Battery use , Shift , etc to provide additional data whilst riding.
Add in a lightweight aluminium frame & 27-speed Shimano M370 system and you’ve got a bike that offers seamless climbing. For the descents, there’s the VS7.0ER1 Z.Star disc brakes. A Suspension fork with 120mm of travel allows you to tackle trails with ease, while double wall alloy rims and Kenda tyres provide excellent grip on the ride down.



With a large battery capacity of 10Ah and a range of up to 40miles per charge the VS7.0ER1 is very capable of going the distance. With a frame-mounted battery on the VS7.0ER1 down-tube, weight is balanced against the rear mounted hub motor providing an improved ride quality, over those with rear-mounted batteries.


The VS7.0ER1 is built around a fantastic XD brushless 48v 250w rear hub electric motor system, seamlessly integrated into the rear wheel, providing improved traction and controlled handling.




The power control in the system is delivered courtesy of a premium Holzer sensor, which gradually eases the power in and out in response to your input, providing a natural ride characteristic and a real reason to upgrade from more basic speed sensor systems. The quality of the Torque sensor is really notable when accelerating out of corners and make small, or when making tighter intricate manoeuvres.

Jac's Electric bikes had set out to resolve the dilemma of Legality around the restriction of speed when in use on the public highway ( max speed 15.5mph ) and are happy to have introduced one of the first electric bike ranges that combine both configurations! We have developed a unique system that allows the user to swop between two modes depending on whether you are on-road or off-road, allowing you to unlock the full performance where it is safe and legal to do so.
