i suggested moving the magnet disk closer first ;) and if then your problems persist and your convinced its a controller issue the #1 controller issue to rule out is the mosfets.. edit.. also the ebikes.ca info is worth saving a link to for future ebike issues..

next time i need a dick to design something useless i know where to go.

The Hailong battery and its mount on my 2nd bike have both been through the wars with sun warped plastic and some of the securing lugs have snapped off on a very bumpy rd/track the battery can jump out of position momentarily disconnecting itself. Strapping the battery down with a cable tie...

Visit www.ebikes.ca ->Learning->Troubleshooting for a mosfet test walkthrough to test your controller, meanwhile minimise the magnet ring-sensor gap.

My encouragement to have an arduino go isnt so much to resolve the above solved problem but to expand the options for solutions to new issues that may crop up possibly unrelated to ebikes entirely. And it can be fun, although the whole arduino framework was conceived to educate kids it is...

Using google to look up arduino is the only skill needed to learn.. The #1 Super thing about the arduino framework is that EVERYTHING you can plug into the arduino has its own working example program (in arduino-speak a program is a 'sketch') - And these example programs/sketches are laid out...

google suggests e-08 indicates a throttle issue, disconnecting the throttle should confirm/rule out this hypothesis.. If the throttle it could just be wired up wrong so check the pinout for your throttle unit.. If not it could indicate a hall sensor issue in the motor.. the grin troubleshooting...

top tip!! A spectacles lens cleaning liquid pump dispenser is a solvent resistant free dispenser for 99% isoprop for misting onto labels for an easy peel or cleaning purposes, very little waste as a single spray is absorbed and evaporated rapidly, great for many uses even a portable sanitiser...

#1 check everything is FULLY plugged in 'waterproof' plugs/sockets often include a 'closed tight mark/line, sometimes they have orientation arrows, these need to 'kiss', to be fully home. a simple test of output voltage of the battery post charge should be a good indicator of its health, for...

+1 You beat me to it @Nealh .. In the 2 yrs ive been lurking in here saneagle has helped 100's of ebikes get back on the rd. if he appears terse or short its simply the result of typing the same thing 100's if not 1000's of time..

Yeah - avoid - mine failed.. oxford brand bike bits are just rebranded white box goods.. fwiw after picking up the collapsed bike when loading up outside the supermarket for the upteenth time i opted for a £20 clone of the ?pletcher? style 2 leg jobs it can be a bit tricky getting it to...

The yose controller will just stop applying power to the motor beyond 15.5 mph, it wont hamper you beyond the mass burden pedalling any faster, so if you could pre conversion you can again post ;) . And with motor assist to get you upto and at 15.5 mph you should have more energy to devote to...

Any stipulation on sticker placement?? hmm time for malicious compliance perhaps?? Version #1 complete with the text "FP FAB EN:15194 36v 250w 15.5mph" Printed vertically on 12mm brother label printer tape is circa 15 cm long.. btw FP FAB- Fat Phil Fabrications.. Both Ortler and...

So a diy sticker with a corruption of the actual bike assemblers name/initials, rather than a dodgy bafang counterfeit, would satisfy the regs And remain impervious to future AI scans of police records looking for sure wins for the cps. no doubt a fake bafang sticker could invoke 'fake goods'...

Rather than stick a dodgy and fraudulent sticker on your bike, wouldn't carrying proof of bike insurance ( if covered) legitimise your within regs conversion?

fwiw im a similar mass 90+kg.. and my stock yose 250w rear motor conversion has enough oomph to put a smile on my face as i pull away and speed upto 15 mph still after 2 yrs on it.. Up-slope too carrying a £60 tesco haul.. Btw 15 mph is way too fast for many roads in not peak condition.. try...

Yes but,,, plugging int a charger and forgetting or leaving overnight unattended could be risky, probably not as the charger should turn off when full voltage is achieved, but.... SO while i will charge my bike/battery on the bike in the garage i will also do so using a segment timer to limit...

the spray on 'fixers' used by arts n crafts folk to protect works or the poor mans equivalent (hairspray) might prep the tape surface for printing?? if patient paint on a weak pva solution and allow that to dry first?

Yeah no problems with pas 4/5 on the flat or when no undue load in on the bike, overheating the motor/controller can occur IF the motor is under undue load such as if climbing a hill and slowing down below the above mentioned 8mph speed. Not so much an issue if you grind to 8mph just as you...

perhaps clean the motor with a solvent and seal in the sticker with a few rounds of clear scotch tape ala laptop windows code erasure protection. or apply a seam of superglue along the sticker edge or, smear with a wipe of epoxy ?? or a combination...
