    I need help with my broken charger port on my merida e160 500 ebike.

    Indeed I did have a look. Unfortunately you cannot really see what kind of connection it is due to the quality of the pictures provided If you can see enough to confirm that it is a Shimano plug with proprietary comm's, then that's good info. The point I was trying to make is, there is no port...

    Why spend $2.00 when you can spend $109.00?

    Protect frame bearings from road salt

    That is also my thinking after I had my M600 apart for re-grease and noticed the bearing that needed replacing was the power side under the crank arms. I planned to use a dab of grease occasionally as required, but due to restricted access, first I may try a gentle rinse of the bearing face, and...

    Battery charging question

    The previously mentioned internal resistance means that the battery produces heat when in use. Because the amount of heat is proportional to the square of the current, climbing hills or using a lower PAS generates more heat. Cold increases the internal resistance of Li-Co quite a bit, that's...

    For anyone that wants to DIY a chain lube, here is my winter formula with ingredients commonly available from Amazon Liquid Paraffin (125 ml) – primary oil that is light enough to penetrate the chain while still providing proper lubrication. CVT Fluid (25 ml) – maintains a low viscosity that...

    Battery charging question

    If by "full" we mean 100% of SOC (State of Charge (SOC) with respect to Li-ion (Lithium-Ion) batteries refers to the current charge level or remaining capacity of the battery, expressed as a percentage of its maximum possible charge), any charge cycle of the battery counts as a charge cycle...

    Orbea Rise Gen 0 Carbon - Faulty battery - anything we can try?

    The battery pack will be constructed from multiples of either 18650, 21700, or flat-pack prismatic cells in series/parallel configuration. If any of the cells in the pack have failed due to deep discharge, then the BMS, if working properly, will leave the faulty circuit open because trying to...

    £1000/1500 aliexpress bike

    The components on the Rocket-Pro are entry level (such as the RD-M6100 Derailleur). I'd prefer to spend more, build my own, and get a better bike.

    £1000/1500 aliexpress bike

    You'll note there is something not right with that store: 1: It only has 33% positive feedback, you minimum should not go below 95%. 2: It is listed as being located in Madrid Spain. 3: Although it is stated the store was started years ago, there are only 4 reviews. 4: They simply lifted the...
