Hi y,all id like some tips on how to go about installing a full throttle on a PAS ebike. Any help s appreciated
 
Just to make sure that you know

It you install a throttle then it will not be a legal ebike on UK roads

I'm not sure what the term 'full' throttle means but throttles are legal on UK ebikes as long as they only operate while you are pedalling its just a linear way of adjusting the power rather than stepped power settings the illegal bit is where its a twist and go throttle without needing any pedalling.

If you buy a cheap ebike kit that doesn't have brake cut off sensors for road bike brake levers then unless you buy adapters really the only way you can use that kit on a road or gravel bike is to use a throttle only motor control which is fine if you only use the motor for hills pretty much where your hands don't need to be on the brake levers.

I think that you are saying that it is legal if the throttle only controls the pedal assist power level - rather than it being controlled by a torque sensor or similar???

That seems to contradict what I have been told and have confirmed on gov web sites.
Where did you get it from??
 
"New builds" can only have a throttleif it cuts out at 4mph
Old new builds....if you say it's older than 2016 can have a throttle
The older than 2016 means it has to stick to ALL the pre 2016 rules
which also means a max motor power of 200W rather that the newer 250W
I used to have one - I miss the throttle - but the extra power is nice!!!

Well by full throttle i meant the twist and go, no pedalling, like when tired and no more energy left to pedal. And tys to everyone for the tips
 
GO AWAY - I have one in my garage yes it has a throttle and it is 250w motor :rolleyes:
Just come back from a morning ride and a bloke passed me on a small wheel ebike on the way back
Looked like a normal legal sized motor (like yours) but he wasgoing into the wind and up a hill and not pedalling at all

Were you in Wides around lunchtime??

It could still be used with a bike with a torque sensor although that isn't as clear cut as the torque sensor also controls power levels but I guess you can have the throttle still controlling the maximum level of power in a linear way instead of the stepped power modes of many ebikes with torque sensors. As before as long as you have to pedal to keep the motor on its fine to have a throttle but you can't have a twist and go throttle where you don't peddle.
