Harmonisation with UK law has had an effect on electric bikes with ‘twist and go’ throttles that can take the bike to full speed without the requirement to pedal at all.
A law came into effect on the 1st January 2016, meaning the only throttles that are legal within the UK’s EAPC legislation are those that can assist the rider without pedalling up to a maximum speed of 4mph, also referred to as walking assist mode. In this mode, if the rider is rolling but not pedalling faster that 4mph, the throttle cuts off.
If you bought an e-bike with a full-speed throttle before January 2016, it is still classed as an EAPC and doesn’t need registering or taxing. Only the ones sold prior to this date must be registered and taxed. Practically, you could still buy an E-bike with a ‘twist and go’ throttle second-hand and not be fined, but it would have to have been produced or imported before January 1st.
The throttle can be used off-road on private land, and so for this reason we stock them and can include them with our kits. Every kit we sell can include these at no additional cost, however, we make every customer aware of the legislation surrounding this, and have them accept the terms and conditions to show they acknowledge this. If you would prefer to not have the throttle this is also fine, we would just not include it in the kit.
To add and remove the thumb throttle, the process is simple and takes no longer than 5 minutes. The main EB-Bus cable included in the kit has a connector pre-installed for the thumb throttle. When on road, the throttle can be unplugged to conform with the relevant UK legislation, and when on private land, the throttle can be plugged in and be enjoyed off-road. There is no legislation for off-road use on private land and so using throttles are perfectly acceptable for these applications.
