41.9 kmh NLS suggests the hub is about 270rpm. Are both hubs the same rpm ? 41.9kmh suggests a 317 rpm NLS hub & 29.9 kmh suggests a 240rpm NLS hub but as you say the Lishui may be factory set speed limited.

Orders from China will be back logged as likely extra measures will be in place as well as man power may be down. My order from TBK was mean to be 4 - 5 days that was 12 days ago, the recent progress for it is still pending.

71 miles is possible in the lowest assist mode, you need to ask your friend what terrain, routes and assist level is used and whether the bike is peddled without power.

As long as the battery is good then your 25km ride is approx. 1 hour on a legal 25km pedelecs if you can maintain the 25km speed all the time., otherwise it is likely to be nearer 1hr 20mins I suspect. The ALP by all accounts rides nicely without power so sound like a good choice. Mean while...

Ebay have emailed me to say the seller is open to offers following my looking at the item again. I have replied to Ebay and sent them a piece of my mind and a link to the pedelecs forum where the original link to the theft was posted, I am not holding my breathe that they will do any thing or...

Battery cells shipped from the manufacturer have a SOC of 3.5 - 3.6v for cell life to protect from degradation as they might be two years before being used, this is a nominal charge. A typical lion cell has a useable charge range of 3.2 - 4.2v but keeping them stored at the lower or upper...

It can do if you use the bike a lot more then an unpowered bike. The downside to ebikes is when someone starts using the bike in high assist mode all the time there is little effort needed, I ride mine in assist 1 mostly.

250/350 are the same and likely so is 500w. For some markets more power/ current is used. Try selling a 250 motor to the yanks put 350/500 on the same motor then bobs your uncle. Most 250w marked motors will handle about 22a but not continuously but still can do so for short bursts, these can...

You can fit a double to the BBS if you want lower gearing, 104bcd adapter spiders are available. The smallest inner chain ring you can fit is 32t.

Excellent now up and running again. The simple fixes are the most pleasing.

Also check any wire loom between the two for any damage or unevenness along it's length, tight corners where wires bend are a weak point and potential for a samml wire to break.

All ebikes have an achilles heel an that is the motor/electronics weight when fitted, generally 3 or 4 kg min. Unassisted the weight will make riding a little harder. To keep the bike to minimal weight you need the lightest hub motor and a small battery of about 200wh (21 cells)for 24v or 300wh...

Failure is often just one fet to start with , the BBS is sealed in potting compound. My BBS01 failed first time round in the middle of some woods , power (current surged) intermittently then the controller eventually failed full stop. I think one failed on the high side causing the others to...

In line with Gov advice I again went out shopping for elderly relatives and on my bike again, whilst out took the opportunity first to take some flowers to my late parents grave. Having then delivered said shopping I again vsisted some other bees to carry out a full inspection, subsequently I...

That's the SW way with no doubt, I think I can still hear you LOL.

Sorry PC2017 I change the text as I hadn't read the posters reply properly, but you got the gist of my original text.

Turn the battery off and just tell us if the motor turns anti c/w by hand relatively easy, all geared hubs will have slight resistance and you will hear the clutch whirring as it turns. A video I don't need to see.

Not as he's likely part of the gang that nicked them in the first place.

Ebike batteries most will be a minimum of 3 cells in parallel (21 in total) for 24v and usually 4 cells in parallel (40 in total) for 36v. A 36v battery will charge to 41.5v to 42v for a 36v battery, min usable charge is 32v or above. If you have a meter check the voltage after is has come off...

Don't back wheel the bike, lift up the rear wheel (off the ground ) manually rotate it backwards by hand how does it feel ?
