    izip my1018z motor question

    Hi Drum, the motor looks new but I think it has been used. The ticking is continuous as you turn the output sprocket. Like turning the key in a clock. The noise is only heard counter clockwise which is opposite to how the motor runs when it was on a bike (I think)

    izip my1018z motor question

    Hi, just picked up a izip motor from ebay. It runs ok when connected to a battery and controller. I noticed when I turn the motor cog by hand (not connected to a battery) it makes no noise clockwise but counter clockwise it sounds like I'm winding a clock. I've got a second spare motor and...

    Electric Izip trike

    Thanks Gogo. Had to look up what you meant by design critique, but yes I am. I'm currently trying to get everything functioning and then refine the design. Motor drive is working great (which surprised me) but using the pedals is hard work so is not right. Seating position needs looking at...

    gng kit info

    Nice article - thanks. I'd be happy running my bike at 36 volts - no higher. the motor I have with the gng kit is the 'unite MY1016Z3' ( 350W 24V, 9,47Nm) which is a different motor to those fitted to the izip's in the article. This motor is really quiet compared to the other mid drive bike...

    gng kit info

    took a chance and fitted a 36 volt lipo battery to the bike (charged to 41volts) and it works no problem. The difference between 24volts and 36volts on this kit is at 24 volts it accelerates gently and tops out around 17 mph, with 36volts it accelerates like a demon and I got 19mph out of it...

    SLA charging questions

    Hi, I’ve just bought 3 yuasa rec14-12 lead acid batteries as a stop gap measure until I can get li-ion. My SLA charger when charging has a red led which goes green when the battery is fully charged (so the charger reads). I’ve been told I should leave the charger running for 8 hours even if...

    Izip question

    Thanks, you're right the controller is 36 volt capable. I put the controller on another bike which has another my1018Z motor fitted (as a mid drive system) - at 36 volts the bike gets 24.5 mph without pedaling and 27 mph pedaling - 7 speed bike. I'm not sure if the motor is the 450 watt...

    my 1016z3 sprocket

    Hi, I bought the unite my1020z (450 watt version of your motor) from the same company as you. The motor sprocket on this was not compatible with a bike chain. I contacted the company and they don't sell sprockets which work with a bike chain for my motor. I solved the problem by filing...

    mid drive gearing

    Hi, this is my ebike, it uses an izip motor taken from the wreck of an izip - I think the motor is a 250 watt one rather than the 450 watt (MY1018Z) as I'm in the UK, though I'm not sure how I can tell. I mounted it on a steel bracket I made. The rear cassette on the rear wheel is a standard...

    unite MY1020Z motor

    Hi, I bought a unite MY1020Z motor (450 watt 24 volts) initially to power a home built mid drive bike based on the 'hutchtransfer' bike built by Eric Hutchinson. The motor has it's own reduction gears. Eric used a MY1018Z motor but I could only get hold of the MY1020Z. I thought both...
