IMPORTANT NOTICE

• For use with mini-velo or BMX with the tire sized between 17x1-1/8 and 20x1-3/8 

only.

• Hub nut type rear wheel axle is not compatible with M20-D in standard.

You need to replace the left side coupling (UF-8) with optional "Left Side Coupling for 
Hub Nut Axle".

• Some assembly required. Use correct tools (10mm spanner & M4 hex wrench).

Tools are not supplied in the kit.

• Use the supplied rear quick release skewer for maximum stability.

Minoura is not responsible for any problem caused from using your own skewer.

• Use on flat and level floor or ground for your safety.

• Adjust the roller pressure to the rear tire properly in order to maximize your tire life.

Tire and roller contact will eventually wear both your tire and the trainer roller.

• M20-D is a tire drive model, so if you use M20-D with a knobby tire on BMX, a loud 

noise must occur. To avoid this problem, replace the rear tire to a slick pattern one.

• Do not use M20-D for removing the mud from the tire.

• Adjusting the resistance must be done with the bike stopped. Do not operate the 

adjustment lever (EM-13) while the rear wheel is spinning.

• Touching the spinning wheel and/or any other moving parts while training may cause 

serious injury. Keep children and pets away from the trainer when in use.

• It is not possible to convert the non-remote resistance unit to the remote control 

version one due to a difference in the inside mechanism.

• If you feel any strange noise or smell, stop using M20-D immediately and contact the 

retailer where you purchased the M20-D.

• Any warranty will be void if you use M20-D for other purpose than instructed.

Minorua offers 1-year limited warranty on the resistance unit and 5-year limited 
warranty on the frame from the date of your purchase for any problem caused by 
manufacturer's defect.
Any damage or problem caused by transporting process is not covered under warranty. 
Any damage from shipping or moving must be made to the shipping company.
