    Controller cooling

    So my 48v 15amp controller is in a little bag behind the saddle. I have already drilled some holes in the bag for ventilation purposes because I guessed it might get very hot. Anyway, today in my jaunts round the tiny back roads in the North York Moors, after lots of 10% , 15%, 20% and even 25%...

    E-bikes are great

    So I'm on the edge of the North York Moors, and I had a little ride into the moors this morning and was just struck how much fun it is on an e-bike.

Is there any invention where the assist power is on a "slider" or twist slider so , for example , I can just twist or slide one way for max assist, the other for min assist and in between, the more I slide/ twist the more power...

    How do speed based PAS levels work ?

    So I understand that controllers can have speed based PAS levels or power based PAS levels. For the speed based PAS levels are these controllers just applying maximum power at PAS level 1 until you hit the PAS level 1 max assist speed ? I wondered if it was done on Voltage - so PAS level one...

    Old Carrera Vulcan Bafang rear hub conversion

    My niece (who is medical student) has asked to "borrow" my Claud Butler step through which I converted (which sounds like a good way of getting around campus !) I will have to give her strict instructions on battery care !! So I could do with a "road bike" as well as my Boardman 29er BBS02B...

    Wisper 705 assistance levels

    I was curious about the 705 assistance levels. How do they work? is it a percentage of full power or a maximum speed within a level or both ? (Jan had hers on level 5 yesterday and it was flying along, I think she prefers it in level 3 and then adding throttle where needed.)

    Wisper 705 Problems

    Hi all, My wife bought a 3 1/2 year old wisper 705 with the 575 battery. We tried it out and it was great for a few miles and then the display cut out and the assist stopped working. We put the battery on charge and the same thing happened again after about a mile. The battery went just onto...

    Hi all, My 73 year old mother in law has always been a keen cyclist. She cycled miles (sometimes 50-60 miles) on an old, step through, very traditional and very heavy bike. Over the last couple of years she's done a lot less cycling because of her knees. I suggested a modern lightweight...
