You're absolutely right about inverting the battery.
I have bought the contacts and the proper crimp tool for the motor main board terminals so the next time I have to take mine apart I can make a much longer loom to move the small connectors to the top of the frame (apart from the two main...
The damage to the speed sensor wire will be from a 'fin' moulded inside the bottom cover that traps it to the motor case. I think it's actual job is to trap and damage the wire, and as such, it's always successful. I suggest that you reroute the speed sensor wire slightly and tuck the connector...
China's finest sine wave perhaps?
If you've had a charger failure that was seemingly down to an inverter I'd put a scope on it and soon to see how clean the wave looks.
MOST battery chargers and batteries actually communicate with each other, sometimes via CAN bus, sometimes via UART communication protocols.
An exception is the Spesh SL. The book does say connect before plugging in to the mains, but it seems happy whichever way you do it. I don't think there's...
Most tyres will work fine tubeless you know?
My experience of 'tubeless ready' tyres is that the majority of them have really porous sidewalls anyway, so you need to run sealant in the majority of them.
Maxxis are good at holding air, Vittoria Mazza are good too.
Michelins (I've tried most...
Have you ever removed a motor from one?
The biggest problem is the packaging of the wiring. Whilst the connectors are TECHNICALLY waterproof, the wiring is so ridiculously tightly bunched up inside the motor covers that the 'pull' on the wires prevents the grommets from doing an adequate job of...
I actually fell into the SL by accident. I was riding a full fat bike, but had a daft intention of doing a route near me called the 'Mary Townley Loop' twice in a day, once in each direction. It wouldn't have been possible to do it on one bike because of battery limitations, so I borrowed the...
That's different to my own experience on both types of bike.
I don't think I could get my SL down to 10 miles range, even if I could find a 10 mile long hill to ride up. Is he really heavy/very unfit requiring lower gears to be used? (Covering less distance for a given energy level).
To get...
I have both full power bikes and two Spesh SLs (KSL/LSL).
The SLs are much slower on the steep climbs, but faster everywhere else.
I'm not super fit, but I'm reasonably fit for a 54 year old.
I like doing long rides as a challenge (plus I don't get out as often as I would like to do, so I like...
I've just finished rebuilding the GLP-2 that I bought a while ago.
I've had it painted (he's done a fantastic job, replicating the original decals and text to an incredible detail), fitted a OneUp 180 dropper, EXT forks (I'm still working on fitting the EXT rear shock), MT7 brakes and some...
Polini do offer warranty extensions by way of having a motor service, which is typically 2-300 Euros (depending what needs replacement). For that you get another 12 months warranty, so you can have continuous warranty for 90 pence a day. :-)
Exactly, the rear wheel frequency is halved (usually); but nobody is going to be using a chainring smaller than 30 with a rear sprocket larger than 52, so if the rear wheel speed frequency received by the motor controller is lower than the specified ratio of the cadence then the rear wheel...
