I once went out on my bike with Strava running on my phone. When I got home I forgot to turn it off and it ended up recording a few KOM after I got in the car and did a journey. I left it on the APP for comedy value but it pretty quickly got deleted after a load of "serious" roadies got the hump...

It has been a while since I updated this thread. I managed to build the bike using old parts I had lying around the garage. Since the photo I have swapped the tyres for some commuter semi slicks as the old maxxis were just what I had to hand. I haven't done many miles on the bike but first...

It's been a while since I updated this but I finally made some real progress. The motor also seems to fit a treat, from eyeballing it the chain line looks good. I had run out of argon when I went to weld it, so ended up brazing the mount into the frame.....not the tidiest but I was ready to...

No worries you didn't miss guide at all. I only found out myself that the g510 comes in 3 sizes when the seller I bought it from sent me an email saying they now had all 3 in stock! So I went and measured mine having just assumed it was 68mm, turns out it is 120mm. Note to self, Chinese...

Yes it's home made, pretty basic but cheap and does the job. You made me second guess myself.....yes there's loads, the g510 I have had a 150mm bottom bracket in it. I didn't realise you had to specify BB when I ordered it, so they sent a mega wide one. Lesson learned when ordering from China ......

Only a small bit of progress this week but I'm getting there. I have the plans drawn up of where to cut and the fitting position of the motor mount. Also started to jig the frame up to make sure it is straight when I reweld it

Exactly, I think a lot of the the people are comparing new alloy bikes with £100 quid full steel bikes from cheap stores, they are likely boat anchors yes Thanks, if I am honest I probably enjoy the tinkering and making things more than the "using" them. You learn something all the time.

Lol, it's moved a bit beyond "pedal assist" then :p

The weight issue is a bit of a myth really. Modern Butted tubing means the frames can weigh similar to alloy, it's just the tubing isn't cheap. Look at some of the high end road bikes being made with Reynolds tubing...... As this is a first attempt I've only used mild steel for the mount. If I...

Yep it should be, but depending how you use it the frames can last quite well if not. I'd have it done, I think you could get it heat treated for around £150, so it's not a cheap option but would give you piece of mind

If you have made parts out of carbon before I guess it's possible. The shape of the motor mount would need some kind of mould for carbon wouldn't it? Bafang make an alloy mount themselves, I would have thought it would be neater + easier to use that and weld it to the alloy frame?

Not sure what you mean? You could make it out of anything if you have the right tools.....

Thanks, yes I'm pleased with it so far. Although can already see a MK2 with improvements :D ha, need to finish this one first!

Thanks. I managed to get the whole mount welded up tonight and test fitted. Fits a treat, just a bit of tidying up to do!
