That's a blow. 40kg max then. Battery in a back-pack??

Those rules go back a bit don't they!? Didn't know they had electric bicycles in 1967 & 72.

The first commercially available e-bike electric motor was a hub motor made by Heinzmann in 1922.

 

Dutch electrical giant Philips had a prototype one a year or two earlier.

tandem http://www.bailii.org/images/contextup.png bicycle http://www.bailii.org/images/contextdown.png" means a http://www.bailii.org/images/contextup.png bicycle http://www.bailii.org/images/contextdown.png which is designed to carry two or more persons at least two of whom can propel the vehicle at the same time.

 

It's possible with one set of pedals though. I think it was VeloVision that published a clever compact tandem design built by two women which they rode together routinely.

 

The front rider was upright, the rear rider lower and semi-recumbent, both using the same large two angle pedals on one set of cranks. Very efficient since the rear rider would be driving the pedals though the front rider's "dead" top pedal position.

 

I think this was probably the only time I'd seen a modern fundamental bicycle design change which had never been done before in some form.

Crikey, that's going way back, the battery must have been huge, i remember using accumulators in my radio!

Yes, they were old car style "wet" batteries then!

 

Here's the 1897 Humber e-tandem prototype:

Well i took a punt for the grand sum of.... £20.

 

Stickers say Bike Easy, Supplied by Broadribbs. It comes with rusty bits that were once chrome. A small topbox held on by some rust.

Guy said he bought it from a police auction and didnt have keys or the inclination to do anything to it. Not even check to see if it was complete.

 

Removing the locks to the topbox found the original toolkit, removed the lock to the seat and founf 3 x 12v SLA batteries (10Ah) in a strange case.

 

Checked the voltage to each battery and they are 7 volts. I dont have a 36v charger so will be doing them one at a time to see if they will hold a full 12v.

 

Anyone help on the ignition switch? 3 wires. Red, Green and white. Do i join all 3 or?

 

Indicator switches appear to be seized. No switches for the lights so assume they are on with the ignition.

 

I pedalled it with the switch set to on, But batteries removed and a red light appeared on the display and the horn worked.

 

So it maybe worth trying to sort it.

 

Run it on SLA for now whilst i save for some lithium batteries.

 

Found the controller under the front floor. eek how many wires?

My e-fun scooter

I would love to put a big motor in this if anyone knows where I can find one

There's loads of motors on Aliexpress.

Having a tinker, My CTEK charger seems to be doing its job on the first battery. 12.3 volts so far. At least it didn't flash up dud battery. So hope yet.

 

Any idea on the ignition wires though? Switch on left handlebar causes a red LED to light when pedalling.

 

I think i will play it safe on the weight and keep it below 40kg. There is not really room for 2 people unless you sit right forward.

If that means junking the rear box and forward carrier and swapping the batteries from SLA to lithium i will give it a try. As long as the basic bike works of course.

 

May make it look less like a scooter. Although it does look more like a bike than the above picture.

My scooter switch had 2 red and a green the reds were shorted together and the switch connected the reds to green for on.

Can you dismantle the switch to work out the wiring if no one replies with the wiring.

I just found this, a meter would be able to confirm if it is similar switch wise, it's meant to be a typical electric scooter wiring.

So its looking like they are legal then. I was thinking of getting a numberplate made up with the details on.

 

Seen an advert that has a plate with the makers name, The voltage and motor power output. Not sure if its a shop thing but thought ideal for a following police car.

Maybe less likely to be stopped if keeping my feet on the pedals rather than the running boards?

It maybe more comfortable for me anyway.

 

As long as i keep the speed to around 15mph, Although that does have me wondering how i would tackle certain 40mph roads around here. Would i want to turn right on a 3 lane roundabout, exiting onto another 3 lane road?

 

One thing i have not really seen or maybe i have not looked enough. 12 - 16" wheels/motors that some of these seem to use.

 

Would the motors be a universal size? Or is it possible to buy something unique and not find spares?

 

Big thanks.

 

 

When I bought my bike the dealer advised to keep feet on pedals. I discovered that if the freewheel is sticking and you don't have feet on pedals, when you let go of the throttle the rear wheel will drive the chain and pedals, and as they rotate the pedal sensor will kick the power back in again possibly leading to loss of control!

 

I never went on roads faster than 40mph and in regards to roundabouts I preferred to stay in the left lane and indicate right.

 

Unfortunately I have been off the forum for a very long time because I no longer use my ebike. It has serious corrosion and other issues on the rear wheel, axle, and brakes. I bought the 125cc SYM scooter I wanted last year and have put a significant amount of miles on it. It has not let me down once, is extremely fast and powerful, capable of carrying more stuff, and in nearly 18 months I've covered 50% more distance than I did on the ebike in 3.5 years.

 

At some point I would like to get my old ebike going again but I fear how much more it has deteriorated since I last used it.

Thanks Geebee, The ignition switch is a plastic block thats sealed with hot melt glue or similar.

I have no idea how many wires run to the motor. Guessing its an old bike and just 2 wires. Not one of these fancy modern motors.

 

Lights appear to be standard bulbs not LEDs so they will be swapped.

 

A partially seized slider switch on the left i presume is the indicator. Another smaller red switch. With it on i pedal and a red led on the dash lights up.

No idea what thats for?

 

Looks like the batteries will be charging for a few days. I dont want to fry them so chose the bike battery option on my charger. And having to charge one at a time. damn..

 

Battery connector is a standard 240v kettle style plug. Silly i thought. What if someone plugged the battery or scooter into the mains...eeekkk..

 

Thanks Synthman, I have not looked underneath yet. I do hope its not rotten.

Test meter across the battery plug. One side gives continuity on the green wire and the other gives continuity on the white wire.

 

Battery charging in the shed so no reference as to which is + and - though.

 

I will check as much as i can before attaching the batteries.

 

Silly me, Just thought the negative would give continuity to the battery/switch because it will earth through the bulbs..

 

Silly me. Must be bedtime.

The red led will most likely just be the power on led as they often run regen and the bike will just see it as power on.

The regen, if you live some where hilly basicly removes the Peukert effect allowing a 12 amp battery to give an easy 12 ah of power instead of closer to 6 ah. One possible issue is I dont know how the Lipo's will cope with a fairly crude regen, on mine the voltage would almost go off scale on steep hills.

Glad you mentioned that. Ive seen the results of overcharging lipo's. Although i would imagine it would need a fairly steep hill to put that much charge into them.

 

Just spun the pedals as fast as i can and it only reached 12 volts. But the battery plug received that voltage whether the switch was on or off.

 

Going to be a steep learning curve i think.

 

Charged one of the batteries to 12.5 last night and its down to 11.8 this morning so i think they are past it.

If they all get to that at least you can at test the electrics are working and test the motor on the stand.

I have some spare 12Ah batteries i bought for my FIL's mobility scooter. The batteries fitted are 10Ah but appear to be the same size.

 

I want to charge these a few times to see if they recover first though, before i start cutting cables etc.

 

Going to have a look underneath and crossing my fingers the frames not a rusty mess.

 

Was just about to look for a decent charger but thought what if i up the voltage to 48v. I will wait.

 

So far things are looking good. Tyres hold pressure, It appears complete except the keys. I was expecting to find the batteries and controller missing.

 

£20 well spent?

Only £20 !!!! Got any photos to show us, i'm trying to imagine it!?

All that enjoyable tinkering and think of all that you will learn, and that is without even riding it definately well spent.

Better off causing sparks (if they occur) on this than an expensive e-bike.

Only £20 !!!! Got any photos to show us, i'm trying to imagine it!?

 

I will try to upload one in a bit. Just think of something dragged from a canal thats been there for years and you wont be far off.

 

I got bored waiting for the batteries to charge.. 12 and a bit volts only...

 

 

IT WORKS!!! well on the stand anyway. Joined the 3 ignition wires together. One puts the lights on and the other is the main feed.

 

Connected up and nothing. put the little red switch on and the dash came to life.

Throttle appeared to do nothing. But i spun the pedals with the throttle on and LIFE!!!

 

Seems you need to pedal to kick the motor in, If you hold the throttle power stays on. If you release the throttle then you need to pedal again for the motor.

 

I was the only bidder, I presume because he said he didnt know if the battery etc was in there.

Tried it up and down the road. Only a short couple of minutes, Not exactly a ball of fire but moving along OK. Will be fun finding finding out if it will manage a hill or not.

 

Brakes are awful. Noise!!!

 

Lets see if pictures work.

 

Looks great, i thought it was going to be something a lot older. Nice!

I'm also quite interested in how these moped style bikes are constructed, but the legality issues of using one as everyday transport are still worrying.

 

On this forum I once very naively stated that one of my ebikes was "fully UK road legal", and was gently reminded that hardly any can claim that total distinction, because they need the correct approval plate, as well as being within the technical parameters.

 

So, as has been much discussed on this forum, the UK law on them is hopelessly out of date compared with other countries.

 

As I understand things, we have to rely on the Police's discretion and certain semi-official "directions" about which electric bikes to prosecute, and which ones to ignore. This seems a very poor state of affairs, considering the rapidly increasing interest in ebikes, by people who just want something legal to get from A to B.

 

I think maybe Police "discretion" is going to be a lot more stretched with moped style bikes, compared to conventional pedal bikes with low"ish" power motors attached.

I'm sure there's nothing to worry about. The police like clear cut law to prosecute and avoid like the plague all the vague areas which might involve them in difficulties.

 

A good example is the law against pavement cycling which is full of possible pitfalls. As a result the "offence" is very rarely prosecuted in any way. A batch of the fixed penalty notices were briefly suddenly issued a short while ago following the Met Police crackdown resulting from a spate of cycling deaths, but that brought a swift response from the minister reminding the police of the law regarding the exceptions that they briefly ignored.

 

Since then the norm has returned, meaning the number of tickets issued per year in the whole of London is usually in single figures, only for the most blatant abuse.
