Thanks gents, I've opened up the Fish battery, I get readings for 10 cell groups, all voltages are similar and in range 4.04 - 4.05 giving total 40.5 Fish bms : I have 2 chargers here (1 known good from my bike, 1 that came with the 2 "problem" batteries), will try a few more charge cycles...

@Andy-Mat i didn’t explain it too well, I’m not planning to replace any cells, I’d like to check if all groups are failing it if there’s one group out of balance - that I can maybe charge directly so it’s nearer balanced. @Nealh many thanks as always. After full charge and resting for an hour...

Hi folks, I have a couple of 36v batteries which are not performing well. I’ve seen a few threads on testing each cell group to see if it’s one cell or group that’s the problem. I’m happy stripping the battery and testing it. My question is how do I re-wrap it if / when I’ve fixed the problem...

I'm nearing retirement and have been riding bikes since I was a kid, last year was the first time I've had to build my own wheel (new electric hub, decent rim, custom spokes), it took some time but it worked out fine. I've built 3 more wheels since (changing rim sizes on electric wheels I had...

A friend visited Portugal recently to follow to road race cycle route, she had good expereinces hiring a road bike for a few days, moving to a different town, and hiring again at the new place. A lot cheaper than shipping your bikes from the UK, and zero chance of customs fees to pay / import &...

Cargo is electric cars not E-bikes but it's a harsh example of what can go wrong when you have a lot of high capacity batteries in one place. Scary stuff https://www.nbcnews.com/news/world/cargo-ship-carrying-cars-us-catches-fire-adrift-atlantic-crew-rcna16675 :oops:

Cramlington New Town (Northumberland) was designed with dedicated cycle tracks away from the roads, this allows quick direct access for cyclists. The downside is the tracks were put down decades ago, many are now needing repair or have been repaired badly, others have uneven surfaces. They are...

A thread from last year might be helpful for you https://www.pedelecs.co.uk/forum/threads/ebikes-and-the-unfit-very-heavy-rider-a-cautionary-tale-for-newcomers.40440/?view=date

About 3 years ago I crashed my car into a ditch and wrote it off when taking evasive action to avoid a collision ( I had right of way on a twisty county road, as I got to a junction a car failed to stop at the give-way line and came into my lane, I swerved and lost control - maybe mud on the...

:confused: From the link : E-scooter and e-bike hire companies are often a target for vandals who damage the vehicles or throw them into rivers and canals. In 2018, Mobike withdrew from Manchester after losing 10% of its fleet every month to vandalism and theft. Lime said a vast majority of...

Umrelated but also in the news today, a fire at Bristol has destroyed hunders of rental E-scooters https://www.dailymail.co.uk/news/article-10362367/Hundreds-rental-e-scooters-damaged-warehouse-fire-Bristol.html

Updating this thread as I expect this will be relvant to the E-scooter trails. TFL (London Public Transport) have banned E-scooters following a fire on the tube https://www.dailymail.co.uk/news/article-10292397/E-scooters-BANNED-London-public-transport-one-EXPLODED-packed-Tube.html Newcastle...

Hi, I built a 29/700C rim onto a Yose hub, lesson learned for me are the spokes are different lengths on different sides (the drive side is shorter than the non-drive side). The length you need will depend on the rim diameter, which will be different to mine...

Updated info showing claculations for spoke lengths - useful for anyone rebuilding a Yose hub ;) https://www.pedelecs.co.uk/forum/threads/recommend-me-a-new-700c-rear-wheel-or-rebuild-26-hub.40709/#post-610609

Important notes: Ignore post#3 above, calcs are wrong as hub diameter is 130mm not 120 mm Do not use these calculations - your rim diameter will be different to mine - used as an example only ! An update for future reference : Spokes (qty 40, length 234mm)...

I'm a fan of Ebikes (it's my only transport) but don't forget the damage caused to the environment when creating them. The batteries require mining for the rare earth elements they use, then processing, and shipping around the globe from their origin to refining to production to sale. The rest...

Choice of tyres can make a big difference, I replaced the off-road knobbly tyres on my mountain bike for semi-slick tyres (same size) and it's a lot easier to pedal on the tarmac/gravel tracks I use - so the battery lasts longer. If you're not a regular cyclist your fitness levels will improve...

For background - I was very tempted to just guess which wires went where but knew I'd seen good info on here in the past (very likely yours for an earlier post ;)), I'm glad I spent time to find the link ! I'm using a "was Lisui now KT" kit from Yose. This originally had a 12 magnet PAS, to get...

I've not been using this for a while, now it's back in use one of the first jobs was to replace the "temporary" PAS. Remove the Hollowtech2 axle, remove one of the spacers and refit the axle with the proper PAS bracket (to replace the cableties I was using :oops:) The first problem was the...

I did something similar on a bike with 160mm rear disk, the battery was hidden behind panniers on the rear rack. Display is a neat compact KT lcd4. The kit was a 350w/36v from Yose. It works well but if I was buying again I’d like a motor with more torque and a KT torque (not cadence)...
