Went on a longer ride - its much better - on the flat and downhill can stay at the lower power levels (this must be kinder to the little cog on the back cassette?) and save the higher power levels for lower gears on hills - went up some ridiculous steep ones yesterday

Cable arrived today - reprogrammed it today so level 1=10% power 2=20% power 3=30% power etc and removed the level related assist speed limits, so it just has the same motor assist speed limit regardless of level. What a difference feels like I can add some of my own pedalling effort now to...

I converted my Boardman 29er Pro - nice big frame for batteries, and light. Seemed to work well with the BB02B -needed a BB adapter https://www.empoweredcycles.com/blogs/news/101474694-bottom-bracket-standards-and-bafang-mid-drive-motors and had some fun with the cables that went underneath the...

Thanks - that looks very good value - wondering about the range with 36V/13Ah - I guess I could use any rear rack battery with that - e.g...

So, becoming a bit of a pedelec missionary after converting my Boardman 29er mtb, my wife getting a second hand Wisper 705 and sorting out my sister's 10 year old KTM Macina Cross so she can ride it again (Thanks @soundwave - got the NX branded battery from allbatteries.co.uk) Next project is...

Thanks

My sister has a 10 year old KTM macina that I thought I would get going again for her. I've changed the inner tubes and sorted the brakes but the battery is knackered. It's one of these https://www.bike-discount.de/en/bosch-powerpack-400-frame-battery-white-classic but they won't ship to the...

So we went out together on our bikes this morning and came back with huge smiles on our faces. We had to replace the battery on Jan's second hand wisper 705 last week (the 575 battery couldn't be resurrected, useful lesson buying second hand)and we splashed out on the 700wh version. We did a...

Just bought it - thanks £5.30 inc delivery ! https://www.wob.com/en-gb/books/lennard-zinn/zinn-and-the-art-of-mountain-bike-maintenance/9781934030592

Not for me, the motor is above the chain ring, maybe really heavy duty mountain biking, I'm usually going along tracks of some description, even if they are pitted and rocky. BBS01 is smaller and lighter than mine and probably need less battery to go the same range

I had a 9 year Boardman 29er Mountain Bike with a Large Frame that I just had converted to an ebike . I bought the Bafang BBS02B mid drive kit (motor, colour display and 48v 20A Hailong downtube battery {that just fits in the large frame} for £640 new on ebay). Somebody locally converts them...

Ok thanks everyone, tried using it yesterday - 5 miles until it cut out. Put it on charge, only charged for 20 minutes and ended up less than 40v - tried again this morning - it is gradually getting worse. Spoke to Adrian at Wisper, he confirmed I need a new battery - was worth a try !

OK - tried charging this morning and the charger light was red (charging) for a few hours - charger light turned green (full) and I checked - 41.1V - slightly more hopeful. I have put it back on the charger until tomorrow even though the charger light is green(battery full) and report back

OK - the charger light turned green indicating the battery was full and I checked the voltage :41.1v - that seems more hopeful. I've put it back on the charger and I''l leave it on for 24 hours (even though the charger light is green) and report back

Hi all, so my story - also posted in wisper clinic I bought a 3.5 year old wisper 705 with the 575 battery for my wife off Facebook marketplace. When it arrived we did a quick round the block - all seemed ok. My wife cycled to the farm to get some eggs but on the way back the display went off...

Hi Al, We've just bought a 705 with 575 battery with very similar symptoms - what was the outcome in your case ? Pete

Hi all, My wife bought a 3 1/2 year old wisper 705 with the 575 battery. We tried it out and it was great for a few miles and then the display cut out and the assist stopped working. We put the battery on charge and the same thing happened again after about a mile. The battery went just onto...

Hi all, I posted this question elsewhere but I thought I might get a more technical answer here, hope that is ok My 73 year old mother in law has always been a keen cyclist. She cycled miles (sometimes 50-60 miles) on an old, step through, very traditional and very heavy bike. Over the last...
