    Torque Sensors

    Hi . I have an idea for a new torque based sensor, but first some background. As most here already know there are PAS sensors where your cadence is used to activate the power to the motor. There are also torque sensors which act to provide varying leves of power to the motor by sensing the...

    Can the cold weather Freeze the Rear Motor?

    I live in a block of flats and my bike is stored outside in a cyle area for residents.. This morning i got up to find the rear wheel frozen solid, it would not budge. I thought the breaks might have been caught up on the disc so i slacken that, but it remind rigid. Now i have the bike indoors...

    Lockable Dust Caps?

    Have you ever had one of those days, someone at work resents your electrified ride and decides 'just for a joke' to let the air down and bend the tube vales to prevent you reinflating? Or someone new to the bike shed decides to introduce himself by letting down your tires for sport. Well here's...

    Protective Cloating - Overkill?

    I was thinking, would it be overkill to wear a motor cycle or scooter jacket on an ebike? The cost, compared to a regular coat, isn't prohibitive. They are of course designed to cut wind chill, they also come with 'armor' for areas like shoulders and elbows and backs. If you fall off a...

    Best Looking E-bikes!

    26V Battery on 36V controller?

    I'm thinking of putting my old and possibly still useful controller on my old bike. My old bike has a working 26v 10A battery, the controller is 36v 12A. Question, would the bike work? Would the under current cut off prevent the any current getting to the motor? Or is that down to the battery's...

    Should the cold weather affect Battery or Controller?

    Of late the power cuts out for no reason. Power is restored immediately upon turning the key off and on. The only thing i can think of is the weather, which is a bit nippy of late. Also there appears to be plenty of juice in the battery. Would the controller cut out due to the weather? Is...

    Councils considering 20mph zones

    Does anyone suppose this will apply to cyclists, or might this actual benefit the ebike industry? I'm thinking slower traffic in cities, less advantage of cars over bikes, greater the advantage of e-transport. Councils considering 20mph zones - UK News - MSN News UK

    Losening Spokes

    I seem to have a problem with spokes working themselves loose. Its the first time i've encountered anything like this. Is there a standard fix, eg nut sealing gel applied to the thread of the spokes, or would this be down to the way the wheel is balanced?
