For commute riding if not renewing I would leave alone as I would prefer to have the more grip on the front, only you can tell how the handling/grip feels on both surfaces. If road riding all the time I wouldn't bother but as you off road a bit replace the rear for the extra grip and centre...

One sensible option is to consider the battery, try and get a bike with the same battery/ fitting so that they are transferable so can be used on either and can be used for one bike for extra range.

Extra speed is dependant on your hub winding/rpm. The psw power dual voltage controllers have a speed restriction wire that limits to 25km/h unplug it and it will give 30% more speed if you hub can go faster, also speed can then be adjusted via the lcd3. The dual volt controller comes in two...

As a reserve get me home I use a 11ah Samsung 22F pack and it works fine, in pas 5 I see 640w+ with pas or throttle no issue of cut out. Double check all your connections inc phase for a poor contact, dodgy solder joint or bullets/sm connector pins loose or not crimped tightly.

Take out a good spoke and measure it for the correct length. Take a measure from the inside of the elbow to the end for spoke length.

Tubeless ready rim, easier to set up them conventional rims. Various differing trademark names but all do the same thing and should be interchangeable. My new bike has WTB rims/tyres, they call them TCS (Tubeless compatible system).

Buy the kit and put your own sticker/label on, nice professional ones available on ebay for under £3.

Throttle is probably shorting and corrupting the pas as it overrides pas when used. Very strange you are having all these little issues as my Yose with KT 20a dual volt controller has been faultless.

I wasn't expecting much success as I was using the supplied standard non TL clinchers with a TL rim, the first one needed a few goes however then I primed the rim and bead and it did the job. Rear one went first time after priming. TL's have a better bead so probably may have got away without...

A quick look everything doesn't show very well to much of a birds nest, pics will need to be better with wires & connector more definable.

The test isn't for a one piece wire but a gated/switch component. The test for V/+ to phase only beeps when a blown Mosfet is detected and reads 0. Not all meters have a beep option so 0 = beep in this case and test. Read up on Mosfets, they are voltage switch component that open and close...

If using oil don't try and put any in where the cable enters the hollow axle in to the hub. Pawls can stick and may be possible to loosen them but also a pawl spring may have broke or a pawl become dislodged, often the job is removal to simply repair or replace. Which part of the world do you...

Hello Julie, I saw your post #2 before this one. You have posted in the appropriate section, any issue no matter how trivial or technical we endeavour to answer.

Hello Julie and nice to see another lady user on board. Your issue is mechanical rather then electrical, the rear gear cluster mounted (a freewheel or freehub) mounted on a e-hub motor relies on a pawl system to catch on a saw tooth mechanism. As the wheel spins clockwise they catch and turn...

Probably to prevent birds, aircraft & helicopters from crashing in to them.

Contact these guys to see if you can get a spare. https://www.thesportshq.com/cyclamatic-power-plus-cx1-electric-mountain-bike If not we need a pic of your controller and wiring to suggest an option.

There is another player Brose similar drives to the others but again they appear to have had issues and another 20 or so other drives that aren't very common or well known to most on here. Panasonic, AEG are well known names but not many bikes appear with these drives though several years ago...

Why sq wave and not sinewave ? 48v is impressive in pas 5, as you have notice 5 gives 75/80% more power then pas 4.

Manufacturer drives are limited to four. Most common are Bosch and Yamaha, it appears the Yamaha is the more reliable one. Shimano Steps system is out but not many use it on mtb at the mo, Wisper bikes are about to introduce it on their new range of pucker mtb's. The other big player is Bafang...

They are after market kits so only suitable for DIY/homebuilds or Darren at Brightonebikes offers a bespoke supply and fitting service.
