Technical questions

How far is a battery charge?

Basically, the ONwheel is designed to provide extra power on certain sections of track. The range of the battery charge is therefore dependent on the user behavior.

Mathematically, the battery is sufficient for 60 km, if it is driven continuously with 80 W power. This is of course very theoretical. In practice, many factors are important: weight and the cyclist’s pedal input, tires and ground or inclination of the track. When driving long slopes with little endurance, the battery can be empty after just 7 km. But if you are in good condition and the ONwheel is only needed on one or the other climb, you can reach easily over 60 km.

Can I use the ONwheel without an app?

Yes. Each kit includes a power regulator (+ and – buttons) that can be mounted on the handlebars. With the regulator power can be adjusted in five stages from 0 to 100%. The app provides following benefits:

    • Adjusting the start speed for gentler flipping up of the motor.

    • Change the country-specific limits with activation code.

    • Personalizing the power levels.

    • Checking the motor parameters.

    • Map function. With new APP with WLAN (electronics from 2018) this is no longer available.

Can the engine be used as a generator?

With our design, this is not possible for technical reasons.

Can Bluetooth or WLAN be switched off?

No, that is not intended. The power consumption is so low that the driving performance is not really affected. Also from a radiation point of view a switch off  makes no sense. Alone the ubiquitous mobile radio transmitter expose us constantly to a much higher radiation than communication-module can produce.

Which tire should I use for the ONwheel?

When choosing the tires, you should make sure that it has a continuous track (tread center). We advise against mountain bike tires with coarse middle cleats. For a mountain bike we recommend a tire, such as the mountain bike tire by Kenda, with a continuous center profile.

Does the engine run if I do not pedal?

When delivered, the ONwheel is set to stop and fold away from the tire when not in use. When you start kicking again, the engine starts again and works on the tire.

In some countries it is allowed to run the engine without kicking. For this reason, this option can be activated via the app. The optional throttle grip can be used to regulate the power like a moped (no longer available on the model from 2018). However, pedaling is always necessary to start, since the engine kicks in only at least 6 km/h.

Can the engine be secured?

No. An engine that is not there is the best theft protection. Therefore, the engine was designed so that it can be removed in seconds.

Buying decision

Can the engine be operated legally?

All ONwheels are designed with a power of 250 W and max. 25 km/h and can therefore be used legally in almost all countries. The higher power of the engine can only be unlocked via our app and an unlock code which needs to be requested (internet connection required). This option is intended to enable higher levels of performance in countries where this is allowed, such as Austria, Switzerland, USA.

Where can I test the ONwheel on site?

Currently the ONwheel is only available to order from a few dealers. But we are currently working on an international sales network.

Where can I find the app?

The app is available for free download from the Apple App Store and the Google Play Store.

Is there a requirement for type approval for certain pedelecs?

There is no obligation to type approval for certain pedelecs: Since November 9th, 2003, the new EU Directive 2002/24/EC is applied for type approval of two and three-wheeled vehicles in all EU Member States.

According to Chapter I, Art. 1 (1) of this Directive, a Member State is not allowed to edict an obligation for type approval “for cycles with pedal assistance which are equipped with an auxiliary electric motor having a maximum continuous rated power of 0,25 kW, of which the output is progressively reduced and finally cut off as the vehicle reaches a speed of 25 km/h, or sooner, if the cyclist stops pedaling, nor to the components or technical units thereof unless they are intended to be fitted to vehicles covered by this Directive”

Can I return the ONwheel if it does not fit my bike?

if the ONwhee does not fit on your bike, we’ll take it back within 14 days. Please make sure that when trying no traces of use remain on the ONwheel. Should a mishap happen, we will send you an offer for a value adjustment.

Please note that we have no possibility to take back a used engine after 14 days.

Does the ONwheel fit on my bike?

Can the ONwheel be operated on a wheelchair?

Unfortunately, no. However, we will address the topic in the future.

Can the ONwheel also be mounted with rear suspension?

This can not be answered across board, as it always depends on the suspension. In general, however, it is rarely possible. More information on this can be found under “Mounting”. When in doubt, please send us a picture of the area between the bottom bracket and the rear wheel (taken from below).

Hub gear with withdrawal, does it work?

Yes. This is not a problem because the engine transmits its force to the tire and thus is not involved in the power transmission of the chain.

Is mounting on a carbon bike possible?

Unfortunately, no. There may be exceptions, but usually there is not enough room between bottom bracket and rear wheel to mount the motor of the previous mounting plate. In addition, the crank arms are so close to the bearings that no sensor plate can be mounted here.

Chain cover, a problem?

It happens again and again that the retaining plates from the chain cover are in the way of the PAS. However, if the magnetic disk for the PAS can be mounted on the left side, this is not a problem. For more information, see Mounting.

Can I mount the ONwheel to my Brompton bike?

Unfortunately no, because folding wheels can cause assembly difficulties.
