Any questions? - We have the answer!
Here you will find a summary of frequently asked questions about our online store and our products. However, if any of your questions remain unanswered, just give us a call or send an email to firstname.lastname@example.org.
We are working on adding a corresponding search bar to the site. Until then, we ask you to use the page search function of the browser (usually accessible under Ctrl+F). Links work via right mouse button -> open link in new tab.
Basically, it can be said that our conversion sets can be used wherever the motor can be mounted. Especially with mounting widths of 68-120 mm, this is possible without much effort.
Here are some bike types:
You are welcome to send us a request if you want to electrify failed systems. In many cases, with a little craftsmanship and the right adapters the conversion is feasible. If the battery does not find a place on the bike, the use of a backpack battery is also possible.
If you don't have a bike to convert yet, we recommend that you consider the following when buying a bike (new or used):
Bafang BBS engines (01/02/HD):
- BSA bottom bracket: easy assembly, no adapter required.
- Bicycle frame made of aluminum (no carbon): easy mounting, no adapter required
- Consider space for bottle cage battery in frame triangle (consider rear suspension)
- Front better 3 chainrings: optimal chainline after conversion more feasible (see point chainline)
- Steeply rising down pipe: thus more ground clearance after conversion (motor position higher)
- If possible, no protruding parts in the area of the motor position
CYC X1 engines
- BSA or BB92 bottom bracket
- Bicycle frame made of aluminum (no carbon)
- Consider space for bottle cage battery in frame triangle (consider rear suspension).
- If the alternative motor position is to be achieved, then the rear suspension and the shape of the down tube should also be considered
Of course, bikes can also be converted, which do not comply with the above points (other bottom bracket, carbon frame, etc.). We would like to show you herewith only the most optimal conditions for conversion.
In addition to the engine (incl. controller), the following components are required:
- Speed sensor (already included with the motor)
- Mounting material (already included with the motor)
- Main wiring tree (already included with the motor)
All other components - such as throttle, shift sensor, brake sensors, etc. - are not absolutely necessary for the use of the system. However, we recommend the use of the shift sensor (for derailleur and hub gears), as well as the corresponding tools for assembly.
The assembly of the individual components is simple: remove the bottom bracket, insert the motor and screw it tight, attach the battery to the frame, mount the display on the handlebars, and the rest consists of wiring with plug connections. So no drilling or soldering is necessary here and can be easily done yourself with a little manual skill. For the assembly of the engine special tool is necessary (ring wrench or 2 nuts) - you can find this in our store under ACCESSORIES / TOOLS. Otherwise, only standard tools (Allen key, pliers, ...) are required.
For the assembly of the Bafang engines we have created a video (see under INFO / VIDEOS). Also for the assembly of CYC motors there are videos from the manufacturer. The link can be found directly in the article description.
The chain line shows how the bicycle chain runs between the front chainring and the rear sprockets (cassette). After the conversion, there is only 1 chainring at the front. The optimal chain line you get so when the chain runs parallel to the frame (straight) and is located at the back of the middle sprocket. Thus, both the small and large sprockets of the rear cassette can be reached without the chain running very obliquely. This protects both sprocket and chainring, as well as the bicycle chain itself. It also reduces wear on these components.
So that you can see what offset you need on the front chainring to achieve an optimal chain line, we have created a template for this. You can find them in the download area under "chainring". The templates can be printed out 1:1 (A4 format).
There are various bottom brackets, whereby a basic distinction can be made between screwed-in (e.g. BSA, ITA) and pressed-in (e.g. BB92, PF30) bottom brackets. Here you will find a good overview of the different bottom brackets.
To do this, we recommend that you turn the bike upside down. Then the frame width can be conveniently measured at the bottom bracket.
(Tretlager = bottom bracket)
In the following two pictures you see the bottom bracket from below. Only the frame width is measured - it should be noted that no bearing shells adjacent to the frame are also measured:
|Frame width 68mm||Frame width 90 mm, in this picture the bottom bracket has already been removed|
If you are not sure, we recommend removing the bottom bracket. Then both the width and diameter of the bottom bracket can be determined exactly. Otherwise, we will be happy to help you - just send us a few photos by e-mail (email@example.com).
The following settings can be changed on the controller (excerpt):
- Max. Power
- Power in the respective support levels (0-9)
- Power when starting
- Sensitivity of the motor
You can find more information under DOWNLOADS / CONFIGURATION. We have also written a blog article about this (see BLOG).
The settings regarding max. speed, as well as wheel circumference, time, etc. are made on the display.
There are 2 possibilities here:
- via programming cable and laptop / PC - Bafang motors
- by smartphone app (Bluetooth) - Bafang and CYC motors
You can find the programming cable in our assortment, the corresponding drivers and software can be found under DOWNLOADS / CONFIGURATION.
Programming via Bluetooth is only possible for Bafang when using the Eggrider V2 display (Bluetooth function). The CYC motors can generally be programmed via Bluetooth - regardless of the selected display.
According to customer feedback, the display works with the following Fischer bikes:
EM 1723, EM 1724, EM 1726, ETH 1861.
Not compatible with: ETH 1722, 1865 Bafang Maxdrive, ETD 140
This information is without guarantee. Our Bafang displays have a green 5-pin HIGO round connector. If the model of your Fischer E-Bike is not listed above, please feel free to try. If the display is returned to us in mint condition, then we will also take it back and refund the purchase price.
We will be happy to receive your feedback regarding the compatibility of the DPC-18 display and the Fischer e-bike and will add to this entry. You will help other interested parties - thank you.
Bafang is a leading manufacturer of e-components and complete systems. Especially in the field of e-bikes and e-scooters, their products are very popular. The headquarters of the company, which has around 500 employees worldwide, is located in Suzhou, China.
It depends on your requirements:
- light weight, very small support up to 250 Watt: BBS01 (250W)
- light weight, a little more support and power: BBS02 (500W)
- robust motor, a lot of support, proven and powerful: BBSHD (1000W)
If you need even more support / power, then we can recommend our CYC X1 PRO motor.
No - the Bafang BBS motors do not have a torque sensor, but are equipped with a cadence sensor (PAS sensor). This means that the motor support is generated according to the crank movement (cadence) and the selected support level (display). In addition, these systems are also additionally controllable with throttle grip / throttle lever.
The CYC X1 PRO and X1 STEALTH motors are equipped with a torque sensor. You can find more details here (description below)
The Bafang BBS motor (BBS01, BBS02 or BBSHD) can be used without battery without any problems, as it has a hardly noticeable pedaling resistance.
Yes, the Bafang BBS motor can be used - in addition to the use with derailleur - also with hub gears. The installation and also the use of the system works the same. When using the unthrottled 1000W BBSHD motor, we recommend you regarding hub gears to use only the Rohloff. Experience shows that this circuit is the only one in the range of hub gears, which withstands the forces of the motor.
Yes, our gearsensor can be used with both, derailleur and hub gears. The operation is simple: The shift cable is passed through the sensor. As soon as this registers a pull on the cable, the motor support is interrupted.
The Bafang BBS01, BBS02 and BBSHD system also works without the use of brake sensors. These are optional and provide a faster interruption of the engine power. The operation is simple: as soon as the brake levers are applied, the contact with the motor is interrupted and thus the power is stopped.
We offer brake sensors for both V-brakes (cable brakes), as well as for hydraulic brakes
No, this does not work because of the freewheel: This allows the motor to move the chainring forward without moving the cranks - the freewheel decouples the cranks from the chainring. Therefore, the chainring (and thus the chain) can not be moved backward by crank movement (only forward). Thus, after the conversion, the backpedal brake is no longer "accessible".
We recommend the use of lithium-ion batteries, where the (nominal) voltage should correspond to that of the motor system. Our range includes the following Bafang systems:
- Bafang BBS01 36V: use of 10S batteries (=36V).
- Bafang BBS02 48V: use of 13S batteries (=48V)
- Bafang BBSHD 48V: Use of 13S (=48V) and 14S (=52V) batteries possible
We recommend you to read our article descriptions - we tried to give you all important information.
The batteries are available as bottle cage battery and / or backpack battery. If neither of the two comes into question for you, then we can also offer you custom batteries. These are manufactured according to your wishes (cell type, dimensions L/W/H, connection cable - length and plug).
The 1000W BBSHD motor is specified everywhere with 48V, but our BBSHD motors can be used with both 13S (48V) and 14S (52V) batteries. If you receive the error message 07 (High Voltage Protection) on the display when using a 1000W BBSHD motor with 52V batteries, please contact us. We will be happy to help you.
This is only possible with the Bafang BBS01 and Bafang BBS02. The Bafang BBSHD motor is already available in 4 versions for different bottom bracket widths from 68-120 mm. You can find more information about this and the exact dimensions of the motor in our blog post.
The two motors BBS01 and BBS02 are suitable for bottom bracket widths from 68 mm to 75 mm in the standard version. For widths over 75 mm up to 93 mm, the installation of the axle extension (art. no. 1419) is required.
