VELOSPEEDER

Retrofittable Durable Service-Friedly

FEATURES AT A GLANCE

Thanks to only 500 grams of motor weight, the VELOSPEEDER e-Bike drive becomes a standard component for normal bicycles, which is optionally available upon demand. A good drive performance of this full-fledged lightweight bike motor at the lowest possible weight increases the action radius when cycling. When not in use, the VELOSPEEDER can be folded away completely. This energy-efficient e-drive for light electric bicycles is extremely maintenance-free. A friction ring will need replacement after appr. 7,000 to 10,000 kilometers / 4,350 to 6,214 miles. Apart from the friction ring, as well the other motor components are largely maintenance-free. The rolling of the friction ring on the rim flank is defined in such a way that the service life of the wheel is not measurably affected by the friction wheel motor. At the same time, the parts of the entire drive train are relieved by this lightweight e-bike motor. The environment is also relieved. It works 10 times more energy efficient than a moped with combustion engine. With the VELOSPEEDER, GENERATION GREENTECH decides in favour of mobility that promotes movement and is climate-friendly.

EXPERT INFORMATION

Operation, brief overview

Motor handlebar switch (index triple)

Gearshift 1: Motors folded away, switched off, no additional idling friction

Gearshift 2: Motors folded on, motor assistance switched on when pedalling

Gearshift 3: Motors folded on, increased contact pressure (in rain)

The pedal sensor on the pedal crank (seat tube mounting) starts the motor when pedalilng. Fine adjustment of the motor parameters on the controller.

Upon active command, the VELOSPEEDER can switch from e-bike mode to normal bike mode at any time using the switch lever on the handlebars, in a matter of seconds and independently of the pedal sensor.

Technical information of the drive

 Propulsion (thrust) WITHOUT pedal movement

4kg (40N) per motor pair type 3125 short / 2kg (20N) per single motor
6kg (60N) per motor pair type 3135 long / 3kg (30N) per single motor

Depending on the motor type (3125, 3135), the motors can handle a gradient of 4% or 6%, at a total vehicle weight of 100kg, WITHOUT pedalling.
From a given gradient, the VELOSPEEDER subtracts 4% or 6%, depending on the motor.
Halving the gross vehicle weight to 50kg will double the climbing ability with the e-drive.

With gross vehicle weights above 100kg, the climbing ability with the e-drive is reduced.
With good pedal power, sporty cyclists can manage motor-assisted climbs at about twice the speed (on smooth asphalt).
Even with motor assistance, climbs are best tackled in easy gears at a high cadence.
The VELOSPEEDER does not increase the range of use of a gear shift.
The VELOSPEEDER optimally supports cyclists who basically master their terrain without a motor.

Limits of application range

120kg total weight for solo bikes (bike including load, rider).

The weight of commercially available electric bicycles is about 10kg more than that of non-motorized bicycles. Not only the motor incl. gearbox and battery cause additional weight, but also the motor mount with the necessary reinforcements on the frame.

The VELOSPEEDER does not require any modifications or reinforcements to bicycle frames, because the operating loads caused by this motor are always significantly less than the already existing loads on the bicycle frame, due to rider weight, drive train and brakes.

The total weight of the bike actually increases with the VELOSPEEDER only by the 1.6 to 2.5kg stated by VELOGICAL, depending on the equipment.

HOW THE VELOSPEEDER WORKS

The VELOSPEEDER is a so-called friction wheel drive. Its potential to become the “standard motor” among e-bike motors distinguishes this approach from all current e-bike concepts on the market – from e-bike retrofit kits to OEM solutions.

Two small electric motors, arranged on the left and right of the rear wheel rim, wedge themselves against the rim flanks when they are energised and thus drive the wheel. The VELOSPEEDER is the only friction wheel drive for bicycles with dynamic auto-regulation of the contact pressure, following the guideline “as much as necessary, as little as possible”. In wet conditions, the e-drive does not suffer any damage, but loses some of its power. At any speed, it will find the optimum contact pressure by itself. No slipping when starting off, no unnecessary rolling friction effects when driving fast.

+++

The clou, by which this patent-protected invention differs from all other friction wheel drives in the history of the two-wheeler, is the geometrical arrangement of the swing axis and the motor mount, as well as the solution of the power transmission at the friction wheel.

Wheel circumference, speed, temperature management (ventilation, electronics, surface) are other flanking factors that make it possible to build these motors so small. The VELOSPEEDER is not a new edition of known static friction wheel drives. With a fundamentally different design, it is the only e-bike drive of its kind that compensates for the system-related weaknesses of previous friction drives.

The attractive motor power of the miniaturized VELOSPEEDER is comparable to the motor power of established e-bike motors on bicycles, in particular related to the character of rear hub motors with fixed final speed, but without restrictions in the choice of gear type, luggage rack and mudguards. The VELOSPEEDER is designed as a standard motor for light pedelecs, light e-bikes by clever use of physical principles, but at one fifth of the weight of usual pedelec drives. The maintenance-free range is between 7,000 and 10,000 kilometers / 4,350 and 6,214 miles under mixed off-road conditions. The material properties of the friction rings correspond to hard, smooth-running skateboard wheels made of polyurethane.

The following factors support the performance of the VELOSPEEDER

The circumference of the wheel, for which the smooth rim flank provides an almost perfect low-wear track,
The high speed of the two small brushless outrunner motors (operated in the lower range of their continuous load capacity),
The open, well-ventilated design for heat dissipation with humidity compensation, thermal protection,
Different motor designs for optimum effect in different speed ranges,
The VELOSPEEDER can be folded away completely as well at full speed – no braking effects due to idling friction
Due to the adjusted rolling of the hard-flexible friction ring on the rim flank, no friction intensive wear occurs, as is the case with brake pads with material heating.
Direct power flow via a short lever arm from the swing axle to the rim, without deflections that reduce the performance.

The discreet visibility of the miniaturized VELOSPEEDER is a decision in favor of efficient functionality.

We consciously neglect the customer need to make an e-bike drive invisible.

The existing electric drive solutions for bicycles usually require numerous preconditions that a manufacturer must fulfill on the design side. They are neither low-maintenance nor durable or universally usable, and often have a high weight.

There is only potential to become a “standard motor” with an overall solution that requires hardly any design requirements on the part of the manufacturer. The solution approach should be low-maintenance and cover a wide range for daily use with a minimum of moving parts and raw material consumption.

Lightweight construction, efficiency, universal applicability and easy reparability – the VELOSPEEDER meets these requirements.

All innovations in bicycle construction that have become established over the long term since the 1980s are dedicated to fulfilling these guiding principles, says a well-known industry expert.

City dwellers in particular want a lightweight bicycle with additional electrotechnical functions but without obstructive effects when additional functions are not in use. The universal VELOSPEEDER from VELOGICAL has the potential to add a new dimension to the strong trend towards electrification of the bicycle market.
