  • Is the JoKer Mini compatible with my bicycle?

    The JoKer Mini can be installed on the majority of city bicycles, mountain bikes and electric bikes, with or without suspension. The JoKer Mini is provided with a 1"1/8 steerer (which corresponds to a 28.6mm-diameter, measurable on the original bicycle), compatible with AheadSet steering system (threadless fork steerer) and with conical steering columns (via a conical adapter).

    A non-exhaustive list of the bicycle models that are not compatible with the JoKer Mini is given hereafter: bicycles with a wheel diameter below 26"or above 29", bicycles with plunger headset (threaded fork steerer), racing bikes, carbon-frame bikes, bicycles with a fork steerer diameter different than 1"1/8 (ø28.6 mm), tapered steerer bikes, bikes without the ISO 4210 certification, bicycles with a front wheel-engine, Speed Bikes (reaching speeds above 25 km/h), specific bikes (recumbent bikes, cargo bikes...).

    At last, the used bicycle must have a minimum crown height of 700 mm from the ground. Click here to learn how to measure the crown height of your bicycle.

  • How can I know if my bicycle's headset is "AheadSet" or "Threaded"?

    Your bicycle's steering system might be "AheadSet" or "threaded". It is important to be aware of which version of steering system is installed on your bike, in order to determine if your bicycle is or is not compatible with the JoKer Mini.

    In the case of threaded steering system, the top of the fork steerer is provided with a thread that allows screwing a nut and a lock nut to maintain the steering system in place. The stem fits into the fork steerer and is maintained by an expander nut. The diving stem can be recognized thanks to its screw on the top of the stem and its long diving tube. If this is the case, then your steering system is "threaded", and your bicycle is not compatible with the JoKer Mini.

    In the case of a AheadSeat steering system, the top of the fork steerer does not have a thread, and the stem maintains the steering system via tightening around the fork steerer. The AheadSet stem can be recognized thanks to its two screws on the side of the stem, and its screw on the top. If this is the case, then your steering system is "AheadSet", and if your bicycle meets the previous criteria, then it is compatible with the JoKer Mini.
