A picture of the bottom bracket and what width it is[for the motor should fit ok ] and the frame size also a picture of triangle would help to see what battery

It should be a very straight forward conversion. Everything is compatible.

Hi Peter.c.

I can't find the information you wanted on Google so I'll go in garage tomorrow and pull the bike out and get all the info needed with pictures because I'll be needing all the help I can get

Thanks

I'll got more information on the bike tomorrow morning but for the meantime can you post some links if possible just to give me a idea what I'll need. I was told by a friend that my bb isn't going to work with any conversion kits from bafang

Your list says SRAM GPX bottom bracket, which looks like this and is compatible with normal versions of BBSxx:

The GPX does come in press-fit version, which is not compatible, but I'd expect your listing to have more info if that was the case, like SRAM GPX PF40 or similar. If it has the knurled bearing holders, like in the picture, it'll be OK, but if it's more or less flush with the BB tube, it'll be a bit more tricky.

Yeah that one in the picture looks just like mine so hopefullyI'll be buying all the gear in the morning after I post some pictures of my bike. I've got £1000 to spend on the battery and bafang plus £200 on anything what's neededfor the rest of the build

There isn't much else you need other than the motor kit. I would get the gear sensor. Without it, you will mess up a gear change sooner or later, which could do a lot of damage and leave you stranded. The gear sensor works quite well and gives you peace of mind.

This is the kit I've decided buy.
BBSHD 48V 1000W with gear sensor and DPC18 with a 52V 17Ah / 48V 17Ah battery.

thanks vfr400 I'll keep you up dated and take some pics of the build when finished

thanks all

I think my bottom bracket is a Italian threaded bottom bracket 70mm

[Ukphil]

It all so says drive side BSA on the bottom bracket

 

[peter.c]

The standard bbshd up to 73mm will fit the bb ok

It's all standard, so nothing to worry about.

I would check you have clearance on the chainstays as those knurled bearing holders can sometimes have the effect of increasing the size of the motor you need. Although the BB is only 70mm you may need to add the extra 10mm width of the bearings each side to get the required clearance. A photo of the BB showing the wider section of the chainstays would help confirm this.

I've been stripping it down to clean everything up and get a new wheel cassette derailleur and brakes

 

[Ukphil]

I'll take it in garden and get better pics if needed

 

[wheeliepete]

That looks OK, I thought it was worth asking/checking as i've had that problem myself.
