Add On Power Cycle for Children

Helping people to get mobile is at the heart of our philosophy; we believe this is especially important for children. Kiddy Viper Add On Power Cycles help kids develop their independence whilst having fun, so much fun in fact they all want to have a go!

Kiddy Viper can be easily transported in the back of your car and be ready to use within seconds.

 The electric system used for the Kiddy Viper is one of the robust e-Bike systems available. Made in Germany to the highest standards it is for it’s size and weight the most powerful there is. By power we mean high torque or great hill climbing capability.

We have tweaked the Kiddy Viper’s electrics to give it slow speed traction control and a speed limit of 4mph. As your child gets older the speed can be increased via the potentiometer.

Kiddy Viper is reliable and rugged and will give years of service, both motor and controller have passed strict stalled condition testing in which the motor and throttle are turned on and the brakes are applied for a set length of time; this test is done to make certain that the electronic controller will not burn out under certain strenuous conditions.

Kiddy Viper electric system has passed a maximum thermal drive test, during which the motor is run as slowly as possible for 10 minutes (motors are less efficient when running slowly), this test is performed to make sure that the motor will not overheat; the classic motor has a built- thermistor to prevent this situation and will cut the power under extreme conditions, once cooled down the motor will work again as normal.


Compact, Lightweight and Long Lasting: Our 36V Lithium-ion battery weighs only 2.5kg yet has an 11.5Ah capacity. The 18650 Panasonic cells used in our batteries are widely known to be the finest available. Protected by a battery management system, the batteries provide a great combination of energy density and cycle life, allowing you to achieve more miles per charge.

Highly Reliable: Battery management technology protects packs from heat, voltage imbalance, and over-current. The BMS (Battery Management System) dramatically improves cycle life and prevents battery fires and explosions. All Li-ion cells benefit from precise battery and pack management technology.

Currently Li-ion battery packs with a capacity exceeding 300Wh are classified as Hazardous Material – Hazmat Class 9 they will not be allowed on aircraft except on cargo flights and have to be packed in carton approved with UN3841 (Lithium Battery and Equipment). We can supply 8Ah batteries if you intend to fly with your cycle.

Docking system

Kiddy Viper Add On can be connected to most rigid wheelchairs via a docking system that is permanently mounted under the wheelchair. Once connected it takes only seconds to dock on.

The rear of the docking system is bolted to either the axle or a bar going across the back of the chair. The front of the docking system is bolted to the bar underneath the seat canvas towards the front of the seat. Some chairs do not have this bar, Kuschall for example. In this case we tailor a bar to the chair, which is then bolted on using clamps or the existing holes.

Fatigue Testing

Our docking system has succeeded in passing vigorous fatigue trials in the USA this included being drop tested 6,667 times along with a multi drum (rolling road) test of 200,000 cycles without failure or the need for adjustment on any component.

(Testing was carried out using the Viper power cycle connected to a Quickie GPV wheelchair)

The docking system will add around 1.7 kg to the weight of the wheelchair and once fitted actually strengthens the frame of the wheelchair.

Please go to the video gallery to view the docking on procedure.

Please note we cannot fit our handcycles to folding wheelchairs.
