Most places that were otherwise inaccessible such as festivals, boot sales, steam rallies and much more are now accessible thanks to the Viper.

Viper Classic Introduction

The electric system used for the Viper Classic 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.

Viper Classic with its traction control and along with the correct wheelchair set up will climb almost any hill.

Viper Classic 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).

Viper Classic has also 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), so 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.

Batteries

Highly 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: The battery management technology protects packs from heat, voltage imbalance, under-voltage 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.

Battery Capacity: The capacity of the battery is rated in Watt hours (Wh) this is the nominal voltage multiplied by the Amp hour (V x Ah). (e.g. 36V x 11.5Ah = 414Wh)

Currently Li-ion battery packs with a capacity exceeding 300Wh are classified as Hazardous Material – Hazmat Class 9 and 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.
