Funnily enough, the same thing happened to me the other day and left me wondering why I couldn't order and ship.

I'm a battery newbie so can I ask, how do you go about checking the capacity of an individual bank (I'm assuming by 'capacity' you're meaning as in measuring Amp Hours or Watt Hours and not just the voltage).

(it's SPRAG clutch BTW) One way to check any sprag clutch slippage on the TSDZ2 is shown in the first 20sec ( here )of this YT clip. I used the method described in that vid to change my sprag clutch. If the sprag clutch seems to not be the problem then as mentioned above, the next thing is to...

I've listened on my headphones to the vid a few times and whilst the noise is clear enough, the source of the noise can't really be determined. Given that noises travel through frames making directional assessment sometimes difficult, how confident are you that it is the motor and not say, a...

I use a 36v 10Ah bottle battery on my 250w TSDZ2 - I ride mostly on assist level one at around 10mph average and my terrain is not overly hilly and get around 50 miles per charge. The battery from PSW Power is under £140 - on the bike it looks like I'm carry a lalrge flask rather than one of...

You say 'good battery' - Good in what respect and what is it's age and how many miles has it been used for?

Without getting into the technical stuff at all, surely an ebike controller is configured to receive the signal from the PAS and without that signal, the controller won't activate the motor.(Different for skate board and scooter controllers of course.) The hall sensors inside the motor are...

The link given above just says that they are 'downscaling' - until details are given, the impact on self-builders for instance can't be assessed. If overheads were one of the reasons for the change, then their prices may be more resistant to the overall cost increases seen in most manufacturing...

I bought the PDF on Wheel Building by Roger Musson (currently £9.00 here) in which he has drawings on making a wheel truing stand from simply found materials. I made one from his design about 6 years ago and have successfully built/trued many bike wheels. It's not a luxury truing stand by any...

What you need is an iwanson guage - ebay less than a tenner (10 GBP) - then google for bicycle minimum rim thickness to which you'll get various answers - a typical range of acceptable minimum thickness is 0.7mm to 1.0mm. Definitely worth getting one - if like me you've been out on a ride when...

No here's a 'battery numpty' view, so treat it cautiously and await one of the forum battery gurus (@Nealh for one) to comment, but I'm wondering if your battery BMS needs resetting which is usually done by charging the battery briefly (how long is 'briefly'?) through the discharge port. As I...

There's every chance that you'll think you've found the perfect bike, then you'll buy it and a few weeks down the road, you'll maybe have a different view - choosing bikes is like that. In my unassisted bike days, I think it was my 4th, maybe 5th bike that I finally settled on and I still have...

Hi @egroover - thanks for you comments - anecdotally it is often the case that providing you change the chain when needed (at 0.7 or earlier), you'll get 3 chains to one cassette, so maybe save yourself some money? (And 3 cassettes to one set of chainrings). You'll soon know if the cassette (or...

Chain wear - I see the points you make and no arguments there, but at the end of the day I've got 3700km out of my chain (I'll probably change it at 4000km to be on the safe side). It could be that if I'd had that same chain on an unassisted bike, I'd have got 7000km out of it, who knows...

Mid drives - if you power up your motor to ride like a Tour de France rider then of course you drive train will wear faster than when 'normal' riding. I'm no slouch and my 9 speed KMC chain (obtained from Decathlon under their own brand name) is JUST showing signs of wear at 3,700km (as...

As further evidence, consider whipping out your smartphone and recording a quick voice memo - an audio recording has the added avantage of capturing emotion too.

I've had a Lidl one for around 10 years or so. The seat pist/frame clamp is crap so I just loop the saddle nose over the clamp arm and use a toe strap to hold the front wheel to one of the stand legs which is fine for derailleur and rear brake adjustment. I keep the stand outside in all...

An interest project if you're into making up circuits on PCBs mounted in say, 3d printed boxes, but I doubt the end result would be more 'elegant' than a bespoke solution from someone like Garmin. Let us know how you get on though.

A spoke tensiometer from Ali Express will be less than £15 - as has been said, watch a few YT vids to see if truing up a wheel is for you. It's not difficult but if you're a DIY disaster then.........?

I've Magura HS33 rim brakes on our tandem and their stopping power even with full luggage and camping kit is more than adequate and have been faultless over thousands of miles - no bleeding or leaks, just new brake blocks. A bit over-kill for a folder but they are very easy and light to operate...
