vintage electric bicycle.

Here is my home built vintage electric bicycle using a xiongda 36v 250w motor and McAllister 36v 4ah batteries.The frame build started when I poped in to Valley scooters in Bolton ( my local ebike shop ).I wanted to see if he had any used battery boxes,I might be able to use for a battery pack I was planing on making.He had one and would take no money for it.I showed him my first homebuild a mountain bike with a frame bag 2 lawn mower batteries and a solar tracker motor that I got off eBay.He said he used to sell them and could not believe the motor was still going.He then said so you like projects you can have this.I was now the proud owner of a Monanna e power girls shoper bike with no batteries and a dead controller.http://images.tapatalk-cdn.com/15/11/13/23a161fda430c14f4b2b74e0421fde37.jpg

I had a old mountain bike frame that the rear end was badly bent.So I chopped them both up.http://images.tapatalk-cdn.com/15/11/13/3e49cc642f03693e5c283d6c38743b23.jpg

Bit more welding and I had a frame with a http://images.tapatalk-cdn.com/15/11/13/c1566162c432a17c809b831008186be6.jpgwide back end.perfect for the xiongda.

The Montana had a wide crank to clear the battery box.It only had a single chain wheel on the front so I did this to my triple chain wheel.http://images.tapatalk-cdn.com/15/11/13/90962c5926846e2ec76c34c056adb422.jpg

The bolts cost as much as the chain wheel.http://images.tapatalk-cdn.com/15/11/13/68b16723758b8def82b6c4e2bf7607f8.jpg

Made my self a sheet steel bender.http://images.tapatalk-cdn.com/15/11/13/f20f077cfc870e349fd6ed67a25e216d.jpg

And made a battery box and controller box.http://images.tapatalk-cdn.com/15/11/13/de3addac255fc4b222e92a6d69b6367f.jpghttp://images.tapatalk-cdn.com/15/11/13/c1553eb9d22417d4c630e97f27b4a559.jpg

1192 miles on the clock now.2 punctures on the rear.I used to get more on a normal bicycle,so fat franks doing there job.xiongda makes noises and clicks on roll back some times.controller gets hot (Dont worry they all do that sir).Might just fill the rear hub with oil.I will have authentic oil stains on the floor then.

Great build, love those forks!

 

Thanks for sharing.

Got them off eBay from India.£27.vintage bike bicycle front yoke springer strut truss rod pair.They have little retaining caps on the bottom of the spring but not the top.I used 15 mm copper end caps that I had.going to get some a bit smaller.I had to put an extra spacer ( I have used a big nut I will replace that with some tube when I find some) under the nuts at the top.These are made for 28" wheeled bikes.The threads on the top are very poor quality.The best solution would be to cut the thread off and redo it,I wouldn't need the spacer then.

Forgot to say.there is no need for the spacer I have fitted.I need them because I have my gear change levers on the handle bar steam.And the bracket for the forks can't go any higher.

Magnificent effort:)

Dave.

You certainly put some work into it. All the sit up and beg bikes in India have those fork bracers/springs that help with heavy loads on bad roads. How does it perform?

With the fork braces I feel more confident applying the front brake.Bicycle forks have a curve in them so they act like a leaf spring.I converted to disc brakes by welding a bracket to the fork leg.so when you brake it is applying a opposite force to the fork leg.With the braces I just have more confidence.If the forks do snap they may give me warning now.I love the xiongda motor.And my batteries where £34 each,I use 2.I went on a 75 mile trip using 6 and still had power left.I lot of this trip was in level 1 assist.

Really nice bike,man.

Really interesting write up and a beautiful bike Craiggor. Great effort.

What a bargain these batteries were, I re-batteried my Cytronex trek using 3 of these and got carried away and electrified my old Hawk Trackatak with another 3 plus a 2 speed Xiongda kit from Panda.

 

I've got 6 fast chargers now!

Hehe , People where supposed to buy one battery and a lawn mover,a hedge trimmer and strimmer.

I'd rather be out on a bike than be gardening.
