To the OP, I’d stick with the bbs02. Replace with an external controller - you can use this for a hub solution if you change your mind later upgrade your gears to a 9 speed XTR shifter, optislick cables. Set up with a tight derailler, your gear changes even under load will be smooth

Your controller is shot I had a near identical experience. Throttle dies, and unless you disconnect it quickly it takes the controller with it. Don’t spring for another glass bbs controller, wire in a kt controller instead. They're bulletproof & a match in terms of power delivery.

Rumour has it that there are (hard to find & more expensive) igh specific gear sensors available that cut power at the ‘start of shift’, as opposed to ‘end of shift’ for derailleurs.

You could make up a small inter connecting cable - I’ve never seen anything like that available off the shelf. Search ebike waterproof connectors on aliexpress to find the 2 prewired connectors. Probably your best bet would be to chop the controller connector off, and attach an (aliexpress...

52t for fast road / commuting. Need to check chain stay clearance though, plus a longer chain may be needed

That’s a great example of a combined approach: disc lock (back wheel) + alarm is potentially a good combination in an urban area

A ‘tile slim’ can be inserted into a hailong battery case. Of course it’s no guarantee of recovery, but the ability to provide the police with an address where stolen goods are present may lead to a positive outcome

Yes, and you’ll need to regrease each and every 500km afterwards as well. It’s a 10 minute job with practice

I’ve used dt Swiss onyx pawls in a bbs01 & bbs02, works great, can’t see any reason why they wouldn’t fit a bbshd - they can be bought in the uk. It’d be wise for you to order some replacement shaft seals (for when you remove the clutch), and also a complete clutch assembly, in case you’ve...

Is it the pawls or spline that’s goosed?

Dahon speed, bbs01, rack battery

My 36v BBS02 500w performs great with a 60cell 35e celled HL battery. I run it at about 22A, and the 21Ah battery is good for about 26 miles OP may need to figure out a way of cramming 60 cells into that triangle if he wants that kind of range

Good work! Get yourself some mobilgrease 28 - it’s needed on the drive gear (chain ring side), every 500 miles or so

Yes it’ll work - it’s my preferred setup You’ll have less acceleration but higher mph

Easiest think to try first - 200 yard full Power brake drag - get them pads smoking

It was hard to find - I ended up going with bmsbattery. 36v 21Ah hailong battery, along with a q128c motor was £400 inc uk delivery. No duty to pay. I wasn’t aware of the inferior long life cycle issues though. Time will tell, but right now the 35e trounces it’s 29e equivalent for me. I’m...

Any reason why Any reason why the Samsung 35e isn’t on that list? My replacement 35e celled battery beats its 29e version in current delivery & range

Recommended on this forum, undergloves still needed when below 5degc though https://www.planetx.co.uk/i/q/CLCARULCRG/carnac-waterproof-crab-hand-winter-gloves

Octalink pas in the link below - you may need to drill & tap the bottom bracket to secure the sensor holder As always, liquid electric tape at the sensor joints & wire entry point works wonders...

Are you running resin pads?
