Hi The whit wire is The variable voltage from the throttle if you cut it the throttle will stop working

to need to find a single white and possibly black wire it will be connected and need unplugging

And I had my snips all ready! ... Frank, on my 24v system the throttle can be used on slight inclines but anything more and its a no go. I dont think de-restricting is going to make any difference to me. Do you?

Hi I think if you unplug the pedal sensor it will work throttle only that will be a 3 pin connector

There may still be a single wire to de restrict the speed For Use in Non European country's

As Frank says, usually a pair of wires with a connector that need to be unplugged to derestrict. Here's an example from another make of bike, in this case below the battery by the bottom bracket:

to resolve this thread, it seems the UM33X has no white wire, and is in fact not restricted.


this message was sent via my ipod, freewheeling at 20mph on my bike

This applies to a number of e-bikes including my own one, the maximum speed set by the battery voltage. You may have noticed the bike is noticeably faster on a freshly charged battery, it's best speed dropping off slightly within about a mile but then staying more constant until the battery goes low when it slows down again.

indeed the case, its just not as snappy if i dont charge it, even when only one light is off the charge indicator, its goes sluggish

I got a throttle today for my 2nd hand UM36X, in the process of installing it I took a couple of snaps of the 10mph restriction wire for future reference to anyone wishing to derestrict their Urban Mover:



After derestriction you may get up to 20mph on the flat with a good, fully charged battery just from the throttle, pedal at the same time and you can break 20mph.

My UM36 is over 4.5 years old and my UM36X is over 2 years old, both have identical controllers, but it appears the controller design has changed since then, removing the white restriction wire, certainly with the 36v UM36SX not having a throttle option.
Personally I find the throttle invaluable with the steep hills round here, without the throttle I have to push a heavy bike up certain long steep hills, but with the throttle the bike carries itself up and I just have to walk it.

Hello Haku

Just also found the white wire which was already disconnected.

I have an urban mover 26 folding bike and the controller says its 24v. I was wondering was yours the same or did you have a higher voltage already on the bike?

I was wondering if I could put 36v through it? But it seems if I didi I would blow the controller
