Hi, I found your website after searching how to fix problem on Viking E-Go

[StevIewonder]

I bought my Viking E-Go bike new a few weeks ago but after only a few rides the bike keeps stalling then engaging for a few seconds then stalling again and so on. Can anyone suggest what the problem is and how I can fix it. My guess is the controller

Couple of things to check. Look at your crank axle and locate the black disc and sensor. Make sure the disc does not have a wobble and that the sensor is within 5mm for the full 360 degree rotation. Check the motor plug to make sure it is properly connected. Keep hands off of the brake levers when not braking. Sometimes even light pressure will active the motor cut off. If, after checking these out and there is no joy, take it back to where you got it. They have a one year warrenty.

The magnet disc should be more like 1mm from the sensor rather than 5mm. If the gap is more than 1mm, you should be able to wiggle the disc closer.

Thanks for the advice. On checking I found the black disc had sheared in two (see photo). Is there any way to repair or do I need to send back to manufacturer? My problem is that although I received the bike new I do not know where it came from. It was won as a prize in a works do at one of the Great Outdoors shops and I bought it from the guy that won it.

If you have the bits, you can glue them back togethervwith epoxy. Don't glue them on the bike. You have to remove the pedal crank to re-fit it. For that you need a crank-puller tool that you can get from Ebay for about £3 or £10 - £12 from a bike shop.

Ask the manufacturer first if not. Motor World do spares http://www.ebay.co.uk/itm/Viking-e-Go-Hopper-Eco-Stepper-E-co-Electric-Bike-Pedal-Sensor-Disc-Bike-Bicycle-/281534919472?pt=LH_DefaultDomain_3&hash=item418cc9f330

You'd still need the crank puller like Dave advised.

Thanks for the advice. I removed the black disc after removing the pedal crank arm and glued it back together and refitted. The bike is now working fine. However I have ordered a new black disc for £16 to keep as a spare. Thanks again for all your help.

Cool glad you got sorted. My daughter has one of those bikes and to be fair, they're not bad at all!
