If the cells are too cold (esp freezing point) they will charge fully voltage wise though cells don't store the capacity as well, voltage will sag and range will suffer. Lithium can withstand cold down to -40c for storage but not for charging. I only charge my batteries the night or day before...

If you have already opened the battery, can you see a white sense wire connector block with 10 or 11 thin wires connected ? Or better still show us some pics of the opened battery. By taking 10 voltage reading via the thin sense wire connector, we can ascertain if any of the 10 cell groups...

When discharging don't go much lower then 44.1v which is 3.15v per cell, your 52v battery is 14s so 14 cell groups in series. As already mentioned if not charging to 100% do a full charge every 6 -10 cycles to ensure the battery cells remain balanced.

Storing/keeping a battery in the cold is good as it prevents cell degradation the issue is with charging lithium is best charged under ambient room temps. Ebikes battery needs to be inside at ambient to charge, cars have systems in place to manage battery temp charging in cold weather.

Just tell them they are wrong and confused, tell them it's an EAPC/e-bike and not a bicycle as there is a difference. It is about education as most people are ignorant to the facts, no use getting angry or abusive. They don't know what thy are missing until they try one, this is the new...

You are wrong on throttles, bikes built before 2016 are allowed throttles. After this date throttles are allowed but have to be configured that you need to pedal to activate them as they are not allowed as a stand alone power source.

Make life easier and replace your tube with a double ended Gaadi tube, since I replaced my old style tube I have yet to encounter a puncture.

Other tyre brands have no issue seating and staying on the rim with high or low psi. In my view the studded ones I have got have a manufacturing fault or possibly as SW has mentioned can't take the weight and force of a rear CST hub, previously it has been used on rear with and without a hub...

Unbelievable !!! New tyre lasted 2.3 miles now of no use what so ever. Tyre decided not to stay on the rim with 40psi had to walk bike home as tyre would not stay put, wire bead failed and 2 strands of at least 12" have come away. Don't think I will be buying Scwalbe spikes again. Refitted...

One out of shape tyre, opp side fits perfect. New tyre arrived with in 48hrs and now fitted.

The mechanical sound can also be phase wire electrical contact noise often associated with a failing controller if phase wire run is sound. The noise can appear to be mechanical and coming from the hub motor though actually a fault resonating from the controller.

1.5 hrs is not good for a 17a battery to charge, should be about 8 - 9 hrs using a 2a input. You can use any 36v lion battery of any capacity, though ideally if you want 25 miles and towing go for the most capacity you can get. Probably the best option is to give Jimmy at BGA/Insat a call and...

Take a voltage reading from the battery output, if the reading is between 41.5 - 42v then nothing to worry about. Though batteries max charge is 42v, there is very little mah/capacity above 41v and what capacity there is will be used up in matter of a few hundred yds of riding. All a higher...

As range decreases the battery will loose capacity measured by mah. Less mah means quicker charging to full so in general you should notice shorter charging times to fully charged. Generally charge voltage will still be about 41.5 - 42v, however in use the voltage will also decrease faster.

Similar to flecc's reply. Once it has hit the cut off power, full assist will only start at the lower speed of 12mph. All to do with the controller software programming so nothing you can do to change it unless of course you are able to up the cut off via a lcd if fitted.

If near Southend, Woosh bikes will fit one for you.

Not familiar with the BB, however the lock ring affair looks similar to the Bafang BBS mid drive. Most BB's are either threaded in or use outer threaded bearings in your case the lock ring is threaded on to the protruding BB thread so does look as it should just slide or tap out. You won't know...

Yes. For rear you will need a specific 180mm rear adapter post to post. https://www.ebay.co.uk/itm/Ultralight-Disc-Brake-Adapter-Rear-180mm-POST-PM-Frame-to-POST-PM-Caliper-BLACK/221808389632?hash=item33a4cf6e00:g:PsgAAOSwFHZaqTqQ:rk:28:pf:0
