Compatibility Thru Axle System
There must be a straight mounting surface for the adapter on the outside of the frame with a minimum diameter of 20 mm.
The frame width between the dropouts needs to be 142 or 148 mm. Postmount points suitable for 160 mm or 180 mm brake disc are necessary.
If there is a straight stop at the left dropout, the frame width must be between 12 and 15 mm. The frame width on the right side must be 14 - 17 mm and there must be a M12 thread with a pitch of 1.0, 1.5 or 1.75.
If there is a 45° cone at the left dropout, the shown dimension must be between 7 and 10 mm.
Compatibility Vertical Dropouts
The hooking area for the axis must be slightly more than 10 mm in diameter or width.
The frame width between the dropouts needs to be approx. 135 mm.
There must be postmount screw-on points for a 160 mm or a 180 mm brake disc.
The frame thickness must be between 6 mm and 10 mm at the axle mounting surface.

Yes, it is even optimized for use in e-bikes.
As we use the freewheel of the electric motors to implement a hill start aid or a roll-back stop, the current version of the hub is only intended for use in e-bikes.
Spoking is described in detail in the manual supplied with the hub.
Beim E-Bike-Fahren wird auf Grund der Motorunterstützung deutlich weniger geschaltet als beispielsweise beim sportlichen Rennradfahren, 6 Gänge sind daher ausreichend.
For example, you can shift gears on hills and do not lose speed if you shift too late. You can also shift gears when the motor is still assisting. There are no shifting errors or misfires.
The hill start assist is noticeable by the fact that you cannot roll backwards in forward gears 1-6. The concept is similar to that of modern cars, but is implemented mechanically and not electrically. If you want to maneuver or push backwards, you switch the twist grip to the "N" position (neutral gear) and can easily move the wheel - however, there is no power transmission from the pedals in this position.
Oil lubrication reduces friction. This results in better efficiency. In addition, oil can be changed in the event of ageing or moisture absorption, which ensures a long service life for the hub.
No, only the original HUB1 oil will work, as this is the only oil that can ensure problem-free operation. Other oils can damage the HUB1 due to various additives. The HUB1 oil has been specially developed for the requirements of the HUB1 and its riders.
No, there is only a grip shift.
No, so far there are only our own brake disks. These have been developed with a well-known German manufacturer and can be used for all standard brake systems. The bolt circle differs from previously available brake discs.
To override the hill start assist and be able to push the wheel backwards.
Yes, if it has 32 spoke holes.
There are currently 135 mm, 142 mm and 148 mm. 150 mm is currently being tested
The sprocket has a Shimano 9-spline mount and can therefore also be replaced.
Yes, we recommend using a chain or belt tensioner for the best riding experience and longevity and making the sprocket wrap as large as possible. The SB One chain tensioner is particularly suitable.
Currently 2.0 mm straight pull spokes. In the future, 2.3 mm will also be possible.
1200 N or the maximum spoke tension permitted by the rim used.
The HUB1 is 'Made in Germany'. This means that all components - with the exception of some standard parts - are manufactured in Germany. Quality control and assembly take place exclusively at Revolute in Germany.
