UK road-legal setup (EAPC rules)
Common EAPC rules for proper e-bike conversion include limits of 250W, 25km/h cut-off, pedal-assist, rider age 14+ and others. Choosing Domex Bikes as your partner for quality workmanship ensures full compliance with UK road-legal setup rules and regulations.

Hub motor conversions (Front/rear)
We do front hub and rear hub conversions to ensure your commute is swift and smooth. Regardless of the system you choose, from Swytch/Cytronex or others, our simple install process covers all your requirements.
