Old Bikey, how a PowaByke morphed to fully suspended.

I'd had my PowaByke Euro 6 for about 14 months when the Panasonic SLA's started to show signs of flagging. My wrists and tail end were fed up with the pounding they were taking on the daily ride to work (some of the shared pavements up the Eastern Road are really, really lumpy) so I decided to get a fully suspended mountain bike and transfer the electrics over.

Fortunately, the place where I work uses a huge amount of 12V, 12Ah batteries so we get them real cheap. I was paying £10 per battery by buying them from work. That's thirty quid per battery change. So, I bought three batteries and took them home. I had two weeks holiday and started the task of getting it all transferred.

I went to Halfords and bought an Appollo fully suspended mountain bike for £150 (about half the normal price). Some careful measurements and battery position trials later I had the layout that would fit within the triangle of the frame. It turned out to be a very tight fit indeed.

I had some 1/4" key metal in my workshop and a MIG welder so I started cutting up metal and welding a battery holder frame together. It wasn't long before it was ready. A tweak here and there and soon the holder was snuggly fitted on the bike.

I made some acrylic panels and sprayed them matt black to improve the look of this strange creature. I spent the next two days transfering the electrics across and fitting the full mudguards to the bike. Another benefit was I'd gone from a 6 speed bike to an 18 speed bike.

Unfortunately the motor cables were too short for me to get the control box onto the top of the frame so I taped it to the side. I fully intended to lengthen the motor wires and move the box to the top and spray it black but I just never got round to it.

There's a picture of the bike attached to this post that shows possibly one of the most comfortable bikes I've ever ridden (except it was darn heavy).

Of course, this is not going to happen to my Wisper :)

excellent - I really wish there were more ladies around like yourself :D - hope that don't sound patronising as I mean it sincerely and I feel strongly about the gender imbalance in engineering in England...

if you have spare time, ever thought of going to schools etc and encouraging younger girls to consider a career in engineering? I reckon something like that bike you made could easily inspire the youth...

That's fantastic Vikki! Does it still get ridden now you have the Wisper?
Hi, Dazzie.

He's a spare. The Wisper is such a Rolls-Royce bike after the old heavy weight I can't keep off of it. My husband says "That's fine but do you really have to bring it to bed!"

Best regards.

Vikki.

That's excellent work Vikki, I'm well impressed. I'd never be able to do that.

Having seen the thread on disc brakes reminded me that the Appollo came with a front disc but i couldn't mount this to a front hub motor. The forks had part of the brake parts welded on but no brake arm mounting studs. I took some carful measurements of the existing studs on the old bike and turned a pair up on my lathe. Since I couldn't weld them on (different metals) I had to do an internal thread and bolt them on. I used stainless steel to make the studs.

- But YOU'RE a girrrrrrlllll!

Girls can't do all that.


P.S. Unless you're older than Flecc and as a Land Girl in WWII you worked in a factory building Spitfires.

BLOODY HELL!

I knew there'd be consequences when they said that Hadron Collider thing behaved erratically and failed to perform in the predicted manner.

You tell 'em Vikki. :)

One day people will separate gender from preconceptions about aptitude and behaviour.

I'm sure somewhere there's a bloke with an embroidery website.

In fact you aren't the first technologically proficient female member, we've had some very knowledgeable tech advice posts from others.

This post of mine from a year ago might be of interest.

Funny you should say that, both my lads were well into cross-point stitching at one time and they were flippin' good at it (winter pastime).

Good for them. I sew as well, hand and machine, my mother was in tailoring and taught all of us at very young ages, so amongst other things I make my own lined curtains and have even made shirts.

So you should be. Here, have a bushel, in fact have two and give one of them to Vikki. :D

You may be on to something there. Explains a lot.

Brill website Vikki. Skulks off feeling somewhat inadequate...:(
