    Waterproofing

    Rotate it 180 degrees or use butyl sealant from a tube or in tape form, it remains plyable/mouldable without cracking or drying out and remains waterproof. Alternately try a good application of superglue around the wire entry and leave to dry overnight.

    Anybody help me diagnose problem with Momentum Model T?

    With no power loss to the led and it remaining live, then the next port of call as d8veh noted is the automatics torque sensor, it might be a re calibration is required or a faulty unit or even a wire fault from said sensor.

    Kapton tape you could use but tricky to get to stick really as little in the way of surface area to stick to. Better to use these proper ones...

    Which one chaps? Carrera Crossfuse or Oxygen S Cross

    A couple years down the line and out of warranty the Oxygen will be easier to repair on the electrical side and battery cheaper to replace later on. Out of warranty work for Bosch drive not cheap if needed and not many seem do the work in this throw away society.

    hi All Battery Cell Layout question

    No pic Billy. On each cell positive use a paper/card gasket to bridge against any shorting when attaching bus bars.

    Conversion Kit for kids bike?

    If the field is wholly private with no public access at all then you can use the bike with the owners permission other wise the letter of the law says NO.

    Organising salvaged cells in a DIY battery

    Laptop cells usually aren't top class amp cells may be 4a rated though may be a from a good manufacturer like LG or Sanyo etc. DO USE A BMS IF YOU DON'T WANT A FIRE. Generally if a cell fails the pack will shut down if charging or discharging. I'm with AK separate the differing capacity (Ah)...

    Organising salvaged cells in a DIY battery

    The high IR cell/s will sag voltage wise much quicker then the better ones, they will either pull the others down to compensate or the weak cell will crash and hit lvc faster. I have some lipo's with the odd higher IR cell ( 20 -37 ohms) and they pull the pack down quite quickly esp under...

    Brake pads

    If rotors have no marking on them then you can presume they are safe for any pad material, then you decide the material for your riding use. Pro's & Con's of material types and use are all over the web so a simple search will help you with your criteria. I tend to buy pads (pairs) cheaply (<...

    Brake pads

    I believe it's down to the tempering of the steel used in the rotor, sintered/metallic pads can cause the rotor to heat up and cause warping usually indicated by blueing of the steel, probably more of an issue with down hill braking. If not using resin pads then pad wear may be an issue as metal...

    Best conversion kit for 27.5 inch hybrid bike

    Converting isn't always cheapest but can be easier to repair. For wheel options you can buy at kit and have the hub laced into your existing rim. Alternately a GSM mid drive (fromWoosh) with external controller will work, no need to worry about wheel size then.

    Anybody help me diagnose problem with Momentum Model T?

    Check all your wiring connections first and check for tightness with all connectors. The fact that the led/lcd & lights stay on suggest that voltage supply/contact isn't the issue. My money is more on that it is likely to be a battery issue with the LVC coming in to play, sounds as if the...

    Organising salvaged cells in a DIY battery

    For 7s it is 7 parallel groups / strings of cell you will need. You can parallel as many as you like in each string. Using old lap top cells with cell with high IR will lead to very poor capacity and dire voltage sag, you may be ok with cells at about 50/60 ohms max. The high IR cells crash very...

    Brake pads

    Check your rotors as some can only use resin , this is usually etched on them.

    Chaos 1600w mosfet replacement help needed

    Sounds like the phase wire sequence order is incorrect or a faulty motor to controller phase wire connection. Check all connections and ensure no one wire is shorting out. If it is phase wire sequence then use the chart below. if yours is unsensored there are 6 combos for the phase. Don't...

    Generic charger mod for Sans and similar.

    You may be ok for 12s as the spec for the caps say there is a 20% margin either way so for 0.2v over might well work as well as the balancing.

    Generic charger mod for Sans and similar.

    You may be right also component wise as well. 2 of my Sans adjust up to 50.2v but another identical looking one doesn't it only goes 45.6v max.
