I’d certainly be interested in buying a V1 battery from you, can you email me at Mefmotorsport@btinternet.com

I rang Gtech and all they had to say was that they no longer stock the V1 battery And the V2 isn’t compatible.

yes but its not so simple, the V1 battery connector housing on the bike has the circuit board for the motor controller embedded in it, the connections to the motor cable and pedal sensor are terminated on the rear of the PCB inside, all potted in epoxy resin, it doesn't look like its meant to...

Thanks, I can see from that picture that the V2 battery and the holder (which houses the motor controller circuitry) is completely different to my V1 battery so it looks to me that it’s never going to be possible to convert V1 to V2. The V1 batteries are no longer available from Gtech which...

Thanks for the link, I'm not sure if its just that part that is required, I really need to look at a V2 battery to see what the difference is. I dont know anyone who has one though. Its possible that the base of the battery is different where it sits in the cradle? Thanks anyway, more...

Can you please let me know where I can buy the V2 battery holder from to upgrade my V1 ebike to take a V2 battery, thanks

So I would just use the 3 phase connector pins and ignore the rest then. The Gtech eBike doesn’t have an lcd display, the only other wire is the sensor in the pedal hub, that plus the 8 pin connector from the motor both connect to the motor controller unit. So I assume I’d use an external motor...

I just pulled the connector apart on the motor cable and was surprised to find that there was 8 pins, 3 thick ones, presumably the 3 motor phase connections then a further 5 thinner pins. Is this a standard motor configuration or specific to Gtech Ebikes?

I meant the standard Gtech ebike battery, although it doesn't work correctly there's nothing wrong with the battery cells, I can just link out the control circuit so it always gives out 36V. I'll have to cut into the motor wire outer sheath to see how many are inside. The pedal sensor comes from...

Thanks for advice, yes, I can easily modify the battery so it just gives a solid 36v output on the 2 pins, that’s no problem, So I will need some kind of controller to drive the motor (3 phase?) and presumably I can use the existing pedal crank sensor , maybe I’ll need a throttle and maybe a...

I've r-posted this to create its own thread. Hi all, I have 2 Gtech city ebikes which were recently subjected to intense heat in a serious garage fire at home. The bikes have fared pretty well, just smoke damaged really but one had its battery fitted which has partially melted and has since...

Hi all, I have 2 Gtech city ebikes which were recently subjected to intense heat in a serious garage fire at home. The bikes have fared well, just smoke damaged but one had its battery fitted which is partially melted and has failed completely. The bikes both work fine on the other good battery...
