Vivax ASSIST - The E-Bike System

Brand:Vivax Assist

Code:Assist-system

ONE BICYCLE – TWO FUNCTIONS - Authentic feeling with the 2-in-1 principle

Cycling is huge fun in a group or with a partner. But cycling with others can also quickly become frustrating. Weaker cyclists trail behind stronger ones for kilometer after kilometer - not really what most riders think of as group cycling.

And that is the situation the vivax 2-in-1 principle remedying:  With the lightest electric motor available anywhere the bike looks as any conventional bike, and it provides that real and authentic ride feel. When the motor assist the legwork, you are still quick and still easy-going. When the motor is disabled all vivax bikes work with their free-running gears without resistance. Get more the extra adrenalin of 100% power to unleash the through capabilities you thought you never had.

Vivax's electric assistance is only usually needed from time to time for group cycling, ensuring the riders remain together.  Electric support takes the strain off hard-working muscles at exactly the right moment. None of the group find the riding too taxing and none find it too easy. On easy routes electric support isn't needed at all, conserving battery capacity and battery life.  Longer and more challenging touring routes are also possible, motiviating and giving the rider confidence. You keep the exhuberence and enjoyment of riding, even on these longer, harder routes.

The low total kit weight of 1,8 kg (including battery) keeps an authentic feeling ride. The 2-in-1 principle means you can easily mix active sports cycling with electronically assited riding. Longer day rides are possible. Vivax's incredible light weight also lets you easily reach speeds over 25 km/h without electronic support.

Sophisticated motor power is hidden in the bike‘s seat tube. It only weights 1.8 kg (inkl. battery). Press the button and the motor delivers 200 watts to the crankshaft. Press the button again and the motor stops.

Without motor power the bike functions as normal without any kind of resistance. The Lithium-Ion  high-performance battery, which fits into a conventional saddlebag, provides you with motor-assisted cycling lasting for min. 60 minutes (6 Ah) or min. 90minutes (9 Ah).

The special design of the drive unit allows it to be built into any bicycle frame with the requisite seat tube internal diameter of 31.6 mm or 30.9 mm and is therefore invisible on the bicycle – except the on/off switch, which is unobtrusively located on the bar end.

The Vivax system has been referred to as Electronic Doping but is best suited for the rider who is struggling to keep up with the group.

Every kit comes standard with :

- Vivax drive unit
- 6Ah accu
- Saddlebag
- Modified alu seatpost
- Wired button
- battery charger

Weight: 1,8 Kg

The optional Invisible upgrade pack makes the system almost completely undetectable with the battery housed inside a water bottle and internally routed through the seatpost.

This system in not available for mail order - it has to be fitted by a trained Vivax mechanic in store - for fitting please call or email.

Who is the drive suitable for?

The motor-gear model is suitable for anyone who uses their bike for sport.

Electric Bicycles

Groups / Families
Cycling in the mountains is both a fun and healthy pastime. Whether you are with family or friends, reaching the top together is a truly magical feeling. However, if your fitness starts to dwindle, the rest of the group pick up speed or perhaps the little ones lose heart on the final ascent, having that extra power at your fingertips makes all the difference. With the vivax assist drive unit, variations in performance are evened out to ensure you reach that goal together. Now, even towing a child behind you on a cycle tour is a pleasure shared. No one under challenged – no one over challenged.

Hobby-bikers
Sometimes you simply lack the confidence to embark on longer cycle tours. Having up to 100% extra power opens up a new world of possibilities: planning tours with new, longer routes over more difficult terrain is now a possibility. Sport and exercise has never been more enjoyable.

Training
People suffering from a range of illnesses are often encouraged to try cycling as a means of rehabilitation therapy. You do, however, need to observe a specific heart rate for this. With vivax assist you optimize your training through maintaining the ideal parameters. Your heart and circulation are strengthened and exercising in the open air gives you an all-over sense of wellbeing.

The lightweight specialist

Electric Bicycle The ultra-light electric motor is unique in terms of aesthetics and function. Build invisibly into the seatpost, the 200 watt motor works directly on the crank. Since the motor comes as a retrofit kit you can install it in nearly every kind of bicycles. You barely even notice the additional weight of just 1.8 kg for the drive unit including the battery. Thus the worlds lightest mountainbike under 10 kg was born. The bike works as normal when the motor is switched off. Freewheel assembly means there is no resistance and you can continue to use the bike as sports equipment.
