I'm lucky enough to have several electric bikes. Some of them have a lot of expensive parts on them. My Rocky Mountain has nearly everything Shimano Deore XT with nice Fox air suspension. It's a joy to ride, and the handling is superb.

Recently I built a bike from a £5 scrap Tesco Bike. The brakes were hopeless, The cheap BB was worn out and the gear cables were broken, so it wouldn't change gear. I upgraded the BB to a Shimano cartridge one for £10, chucked the rakes and fitted Avid Elixir hydraulics for £60. and fixed the gears with a £1.49 Wilko cable. I think if I got one of those chain-wear testers, it''l tell me to scrap it, but I think I'll try and eek out another 5000 miles from it.

I installed the Xiongda 2-speed motor kit, which would be a credit to any bike, even though it's very cheap at under £200 without battery. I now have everything installed, so took it out on the road for a proper ride. It was just as enjoyable as any of my other bikes. Sure, it got me thinking. Everything is working as it should - smooth and quiet - except when the forks clatter over big bumps (no rebound damping). I don't know what size the frame is. It looks like a kids bike, but I didn't have any trouble pedalling it around. neither did Saneagle, who's over 6ft. i just put the seat up a bit.

You know what's coming. I'd be happy with that bike if it's the only one I could have. I've said that before with other bikes that I've tested. My basic conclusion is that you don't need anything fancy. it's a matter of choice what bike you get, but don't kid yourself what you need. Needs and wants often are not the same. Obviously, if you do something special with your bike, like riding in mud or time trials, you need something special, but on the road, it's different.

I'm looking forward to my first really long ride on this bike, and no, I don't expect anything to fall off or otherwise breakdown.

That's a nice looking bike now D8veh. I like the re-inforced seat tube rack. I assume a DIY addition?

What battery do you have on that rack?

I had 10aH of 12S lipos today, so about 3 kg. Next time, it'll be my 4.5kg 20aH 36v battery.

D8ve,
How is the two speed motor going. Have you been up any really steep hills?
Does it compare to a crank driver?

A while ago, I made a crank-drive from a Bafang 250w motor.It has similar power and torque. At 44v, it has enough torque to easily drag my 100kg up a 14% hill without pedalling. At 36v, it can still do it, but it feels like it's struggling. It's a lot better with light pedalling.

I still have this kit if anybody wants it. It worked pretty well.

So what bike do I need if I live in a small flat on the first floor in Central london. With a small lift. An require to sometime carry a friend with me. And hate the rain? :)

I wish I could find those £5 bargain bikes to mess with. I need to look harder I think.

I read an article a while back by an american rider of some repute & he maintains that the average weekend warrior is wasting money if he spends more than $300 on a bike.

Made a lot of sense, but I definitely need to upgrade the tourney derailleur on my bouncer - It's 'orrible :oops:

Is it the colour you don't like? Surely you never change from top gear with that powerful Ezee motor?

I agree with Dave, my first build was a cheapo Asda reflex MTB with an ebay 500w kit on it and I powered it with 3 7ah 12v SLA batteries! It got me to work and back for nearly a year with no issues at all. Now I have a used Carrera Subway with a Cyclotricity front wheel, a controller from Dave and a recycled Momentum 9ah lipo battery and i love it, mechanically the only alteration was the forks which I swapped with some donated Rock Shox judy's. I've a Tonaro sat doing nothing as I prefer my cheap bike!

Still want an A2B metro at some point though.:)

A double-decker unicycle with the passenger wearing a cape to keep you dry underneath. ;)
