If you need a hand to set up/check your new buy over I can pop around to lend a hand , I'm in the Three Bridges area. No charge but love a cup a tea. For cycle clothing I wear Tenn mtb thin light trousers with a knee zip to remove lower leg in hot weather, for tops a lycra looser fit zip front...

You need a screw on freewheel hub kit and a new sq taper bottom bracket for the V12L type pas, a new bottom bracket is about £10 - £12. If fitting a V12L remove the bottom bracket and get the next size up that gives about 8/9mm spacing. Depending on what the gap currently measures (looks like...

WIth the LHS KT V12L to do the job proper you need to get a new Sq taper bottom bracket with a long axle. Take yours off measure it and get the next size up.

52v is 14s although sometimes labelled as 48v is incorrect as the nom capacity is not 48v of 13s. For those speeds/power may be think of upgrading to quad actuating callipers and 201 rotors.

On a ride out the other week I had a play with C2 settings and anything bar value 0 & the phase sync was out and horrible noise from the controller.

Great result and superb CS from Xiongda.

Show us a pic of the rear wheel/gears, how many cogs ? LH V12L pas sensor is for square taper bottom bracket which you have, sometimes you have to replace it with a longer axle shaft for the sensor to fit. You need approx. 8mm gap between crank arm and bottom bracket face.

No. You will blow the 36v controller running @48v.

Not a like for like comparison is it, comparing a brand new batteries range with a very old 8 year old one. A total mismatch.

Set for 100% KC and have the 9 assists, with programming split the Pas levels. 5 for high speed low to med torque and 4 for low speed high torque.

Not often seen though some ebikes have used controllers with potentiometers, If it is possible to introduce one then it would at least help to comply with the speed limit.

O.k if only local but if you do long rides (50-100 miles ) then range is king, change settings to suit your needs and parallel another battery in.

Yalu Electric have one with PAS on their web page. Middle one top line, send them a message. http://www.yalumotor.com/brush_controller/ Here it is on Aliexpress and cheap...

Georgehenry got a complete working one for £100 with a decent battery. At 50 -75 might be worth a punt if battery is reasonable, if battery is no good then by the time you take that cost off seller would have to give you 50 - 75 just to take it away :rolleyes:.

Brompton Nano kit currently on Ebay, working used 1 month currently at £101.

A pair of options via Badass SX2 or Box4, no bike tuning just removes speed restriction if you want to be naughty.

Your controller is a speed controller with no option to wire up a PAS system so you will need a new controller with PAS option. It will need to be a brushed controller if you can find one.
