Installation requirements for your bike
There are only a few requirements that should be fulfilled for the installation of the Pendix eDrive. Please check these in advance to ensure that your bike is retrofittable:
"Must-have"
During the installation of the Pendix eDrive, the bottom bracket of your bike is replaced with the Pendix measuring bottom bracket. The requirement for this is that a so-called BSA bottom bracket is installed. The term "BSA" refers to a type of thread used to secure the bottom bracket to the frame. The left bottom bracket shell has a standard right-hand thread, while the right bottom bracket shell uses a left-hand thread. There are two versions of the BSA bottom bracket type in terms of width: 68mm and 73mm bottom bracket shell width. This is important because the Pendix measuring bottom bracket will be installed with or without a spacer, depending on the width. The width can also be measured while the old bottom bracket is still installed.
On the right side of the bike, the crankset is replaced with a Pendix crankset. This crankset requires 4-bolt chainrings with bolt patterns of 4 x 104 mm or 4 x 64 mm. If your bike does not have the described chainrings, they can be replaced, allowing the Pendix crankset to be installed. If you're unsure about doing this yourself, it's recommended to have the installation done by a Pendix dealer.
The Pendix ePower (battery) and eMachine (motor) require sufficient space on your bike. The motor is always installed on the left side of the bike, opposite the chainrings. The battery can be mounted in various positions. The designated holes for a water bottle holder can be used for this. If the battery doesn't fit in this position, it can also be mounted on the top tube or seat tube using a clamp holder. To test if your bike has enough space for the two Pendix components, we offer a template that can be printed and assembled.
"Nice-to-have"
For the installation of the Pendix ePower (battery), a standard battery holder is included. This holder utilizes the screw points for water bottle cages that are already present on your bike. If the battery needs to be mounted in a different location on the bike, we offer clamp holders for this purpose. For mounting the clamp holder, a band tensioning tool is recommended, which you can also obtain from us.
Safety requirements for your bike
Your bike should be in a technically very good condition and should not have any pre-damages that cannot be repaired before the bike is re-equipped. Furthermore, all safety-relevant assemblies and parts should be intact and not worn out. These include tires, rims, brakes, frames, bearings, handlebars, stem, rear derailleur, driveline. If you have any questions or uncertainties, we recommend that you contact your specialist dealer, who can check your bike.
If you participate in road traffic with your bicycle, please make sure that your bicycle complies with the StVZO. The following points must be fulfilled:
- 2 independently acting brakes
- Front and rear lighting
- Reflectors front and rear
- Dynamo or battery light
- 2 reflectors per pedal
- 2 spoke reflectors or reflective material on spoke, rim or tyre per wheel
- Light-tone bell
Additional components such as mudguards for the wheels, a chain or belt guard or a parking light system are not mandatory, but nevertheless useful.
The same applies here too: if you don't want to put your own hands on your bike, you should have it checked in a specialist workshop.
