I am speculating here but I am presuming that some wedging action of the rollers is to some extent how the clutch works (but is perhaps excessive in some cases), and whats best needed to release the wedge is a short sharp change in speed between motor and hub. Now, I can see how this may not...

The other possibility is that the 'roller' type clutch mechanism is sticking. If you think about it, the rollers engage at the lower motor speeds and sometimes with a surge under high torque. This wedges the rollers. The disengagement on hub motors takes place at the higher speed/ lower torque...

I am just wondering is there any possibility that this problem could be caused by e bikes been fitted with tyres that are more durable but having very high rolling resistance, especially at lower psi. For example, Bicycle Rolling Resistance website tested Continental E.Contact tyres and found...

Is it OK to dispense with the axle (spacer?) nut as shown in photo below. The reason I ask is because I am thinking of fitting a mxus xf07 front hub to an older bike with steel forks but it is a tight squeeze. The bike has V brakes and it would be a more comfortable fit (no need to spring...

I use my bike a lot in the hills and have worn 3 sets on the rear but am still on my second set on the front (in about 3000 miles). My bike has rear rack battery and rear hub and is heavy on the back. I also note (with some alarm) that the rear rim is also worn. The wear line is starting to...

Thanks for info. I was looking before for same and came across info on 11ah version in link below to pdf. The 'smart bms' has a uart with tx & rx wires that are part of the middle battery connectors. I am guessing here but I think the manufacturer/supplier can interrogate the battery here to see...

My bike guarantee from Halfords is very specific here. The battery is guaranteed to 60% of its capacity, which I presume is equivalent to a 40% loss. (The Phylion battery has a 'smart BMS' and the user can view this by holding down the 'on' button for 10 seconds) I have seen this 60% figure...

I agree. I had the exact same problem on pendleton and thought the pawl spring was broken. I ended up removing the wheel and then the freewheel and dismantling freewheel to investigate. The freewheel (DNP) has caged bearings and these, along with the pawls are lubricated with what appears to be...

The Schwalbe 2018 catalog is available at https://www.schwalbe.com/en/catalogesflyer.html Their tyre rating includes road grip, with their e bike 'energizer ' tyre particularly scoring well here, but max sizes is 1.75 to 2.0 inches. (page 12).

I had similar problem with Pendleton from new, with chain falling off onto the outside every approx 70 miles or so. It seems to happen often after long freewheeling down hills. I initially tried tightening B screw but made no difference. I then tried removing two links from chain and this...

After having to tighten some loose spokes, I am thinking the opposite in that I am thinking of changing the 700 X 38C tyres (which are only 35mm wide) for something bigger (as there is plenty of clearance under mudguards). My thinking is that the bigger air cushion (and slightly lower psi) will...

I bought one of these last November online and paid and collected at my local Halfords in the Black Friday sale for use by both myself and my daughter. The bike was at a good price and has a two year guarantee. The bike has a classical appearance and certainly looks sturdy. Since then, we have...
