Electric Bicycle Wheel Motor

The motor-wheel (electric wheel) is installed instead of the front or rear wheel of the bicycle. It is directly knitted into a durable double rim of the desired size. The design allows the use of both disc brakes and v-brakes. Bicycle gear shifting is not disturbed.

Included with the wheel motor is a controller and a throttle stick to choose from. For a complete set, you will also need a battery.

Gear motors

Lightweight (up to 4.5 kg) and freely rotate forward thanks to the overrunning clutch. Suitable for quiet (up to 35 km / h) riding in the city and parks, in pedal assist mode or only electric.

Fat-bike motors

Wide rim long axle motors suitable for fat bikes.

Direct-Drive motors

Universal motors with electric braking function. Faster (up to 60 km / h), more powerful (up to 1.5 kW) and heavier (up to 7.5 kg). For aluminum frames we recommend dropout amplifiers.

Powerful Direct-Drive Motors

Motors for high voltage configurations (77-85 V). Develop a speed of up to 80 km / h. Only using dropout amplifiers or specially designed frames.

FAQ

And my bike fits?
Most standard bikes are compatible.
Seat width. 100 mm for the front wheel, 135 mm for the rear (standard).
A 9-star freewheel fits on the rear wheel (comes with 6).

Better front or back?
Rear.
The front is put if it is impossible to set the rear (for example, planetary gear shift). The maximum power of the front wheel is 1 kW.

Is it difficult to install? I myself can?
Remove the wheel from the bike, rearrange the tire and the camera on the wheel-motor, install the wheel-motor in the place of the bicycle wheel, pump up the camera. Attach controller, throttle and battery to bike. Connect all wires, adjust gearshifts and brakes.
The first time. a few hours, the hundredth. about 25 minutes.

Motor interferes with pedaling?
Geared. no, thanks to the overrunning clutch, it freely rotates forward
Direct drive. a little in the way, but really noticeable only at high speeds.

Traction or high-speed DD to choose?
Traction is usually better. High-speed. for rims 24 “and less.

What about the brakes?
The motors have a disc mount and a strip on the rim for v-brake. In most cases, there are no problems.

Can I charge with pedals?
Theoretically it is possible, but only at DD and high (30 km / h) speeds. Practically meaningless, energy return is too insignificant.

Amplifiers needed?
For Light motor. we recommend one.
For the Classic motor. we recommend two for using recuperation and one without using.

Reliable motor?
10 thousand km in a year and a half without a break for the winter. the flight is normal!

Brake levers are needed or without them?
For a gear wheel. not needed.
For DD. only needed if an electric brake is used with Infineon controllers.

LCD3 required?
Not required, but pedal assist modes (if PAS is installed) can only be controlled from it.
No display is required to operate the throttle stick. But it’s nicer with him 🙂

PAS sensor needed?
It adds the ability to release gas without holding the handle. Sometimes it is convenient, but you need an LCD3 display to change modes.

I want to use the motor as a wind generator / electric cultivator / tractor / caterpillar, etc. Can?
Yes. At least fly 🙂

Types of motor wheels

There are two different motor-wheels that can be used to create bicycles and other vehicles.

motor, wheel, bike, battery

The advantages of such a system

  • The bike is not subject to irreversible changes. Even its appearance hardly suffers. The main part of the device is mounted on the wheel.
  • The motor wheel runs almost silently.
  • Smooth, yet high-speed movement of your two-wheeled vehicle is achieved thanks to the smooth operation of the engine.
  • Climbing the hill is performed with minimal effort.
  • The device has no rubbing parts, so its service life is very long.
  • You can easily remove the device and return the original functionality of your bike.

Features of the installation of motor wheels

Having chosen a suitable motor, you can proceed to the direct installation procedure. It can be done by hand.

The instruction looks like this:

  • To begin with, the nuts that secure the wheel are unscrewed, after which it is removed.
  • The motor-wheel is being installed in the vacant space.
  • After the assembly of the entire circuit is carried out, but the fasteners are only cashing in. This is done in order to check the operability of the device and outline the trajectory of the wiring.

What is a bicycle wheel motor and how to choose it

Many people choose to use e-bikes because they help to ride against the headwind and climb a high hill. Everyone can now assemble an electric bike with their own hands, thanks to the many sets brought from China.

But the electric bicycle only increases the strength of a person, and does not completely replace it. Thus, pedaling while riding an e-bike will still be required, and this is especially necessary when driving up a slope.

Unlike other motorized vehicles, which only have a motor to push the car forward, an electric bicycle combines the power of a motor with the power of the rider. Machines that combine power from different sources (for example, a motor and a person) are called hybrid.

When a person is not sure that a specific set with an electric motor will help climb to the top of a hill, he is lost in thought: what if the hill will be even steeper or longer. And naturally everyone wants the most powerful electric bike kit ever. However, in many cases the most powerful electric motor will be overkill, and you will end up spending too much money and carrying around much more weight than you really need.

You can climb a low hill with almost any motor-wheel for a bicycle. And if at the same time lightly pedal, then you can easily climb a steep hill, even under difficult conditions. strong headwind and heavy rider weight. Compared to conventional bicycles, electric bikes will pleasantly surprise you.

Examples from real life situations

Take, for the first example, a standard motor with a maximum power of 250 watts at 10 km / h and a cyclist who can also bring in 250 watts (not trying hard) to maintain a given speed. Together they deliver one impressive 500W of power.

  • At a speed of 10 km / h, a rider can climb a hill with a slope of 17.5% with 500 watts of combined power.
  • At a speed of 8 km / h, a cyclist can climb a hill with a 17.5% incline with his 250 W and a motor running at 80% at 200 W.
  • At a speed of 6 km / h, a cyclist can climb a hill with the same incline of 17.5% with his 250W and 125W motor running at 60%.

At first glance, these results may seem completely inaccurate, because only the efficiency of the electric motor goes down along with the speed, and it seems that the cyclist can still climb the same steep slope.

This inaccuracy will be resolved when we understand how important a person is to the operation of an e-bike. Let’s see what would happen if the cyclist did not press the pedals at all and all 500 watts (as in the example above) came from the motor.

  • At 10 km / h, a cyclist would only be able to climb a 17.5% incline with the 500 W engine running at 100%.
  • At a speed of 8 km / h, a rider can climb a hill with a lower incline of 17% with a 400 W motor running at 80%.
  • At a speed of 6 km / h, the rider can drive up a hill with a slope of 14.5% with only 50% running of the 250 W motor.

These results are taken from the e-bike calculator with the following inputs: total weight. 100 kg; frontal resistance area. 0.4 square meters; friction coefficient. 0.7; lifting length. 100 m; headwind speed. 10 km / h and rolling resistance coefficient. 0.007.

Race around the city on a self-assembled electric bike with a motor wheel:

Rider strength is most important when you need to maintain speed on an e-bike, because when it drops, engine efficiency is greatly reduced. By analyzing this, you will be able to understand how an e-bike is different from any other motorized transport and why installing geared motors is not always the best choice. It is better not to put a motor with a gearbox in the front wheel at all, because it should have a free roll.

Direct drive wheel motor

A direct drive wheel motor is characterized by two main elements: stator and rotor.

Let us call their features the following:

  • The rotor is represented by a winding wheel axle. It attaches to the bike frame.
  • The stator resembles bushings with a powerful permanent magnet. The spokes and the rim are attached to it, during movement it rotates around the axis.
  • The design in question is quite simple and reliable, since there are no rubbing elements.
  • The advantage is that the power can reach 5000 watts. In addition, the maximum travel speed is 100 km / h.
  • The efficiency indicator is much higher when compared with a gearbox.

However, the direct drive mechanism has several significant disadvantages, for example, friction occurs at the moment of movement. Therefore, pedaling will become much harder. In addition, to achieve the required power level, a device with large dimensions is needed.

Reducer

Its power ranges from 250 to 350 W.

The key features of this device are as follows:

How to Make Electric Bike With 2000W Hub Motor 70 Km/h

  • The reducer is designed to increase the torque, which causes a decrease in travel speed to about 30 km / h. However, due to this, climbing the mountain is greatly simplified, less effort is required. Achieving a similar torque with direct drive is possible only with an increase in power to 1500 W.
  • The design of the gearbox is represented by a combination of several gears. The service life of moving elements largely depends on the mode of operation and correct maintenance.
  • Gears cause noise or hum during operation. In addition, due to the resulting friction, the structure can become very hot.
  • The main distinguishing features are relatively light weight and compactness. Modern technologies make it possible to make a device, the diameter of which is greater than the diameter of the sleeve.
  • The negative side is that the maximum power is about 500 watts.

Torque

When changing gear, torque is always lost. Therefore, it is advisable to always start climbing the hill in the appropriate gear or make as few changes as possible when climbing.

Even a geared motor is affected by gear changes. After the rider changes gear, any engine will have to change the speed. In this case, it will be better if the cyclist gives an extra push through the pedals after the gear change.
The front motor wheel also loses torque along with the rider when changing speed, as they are combined into the same gear system.
