Well, theres one very cheap way, to make your bike go very fast: chuck it off a cliff:eek::eek:........but I don't think that's the answer you want. Another way is to ride it down-hill. Other than that, have a read of this:

Depends how you ride the bike..if you pedal, setting up the bike for higher gearing and getting a bigger battery capacity should help increase the speed..

Assuming there's no way to alter the speed on the bikes controller...if you're riding on throttle only you're probably limited by the controller and/or motor and might need to replace those.. you can buy them reasonably cheap online, but the big cost will be a new battery if you need one..

You can get a few more mph by using a decent battery, but this is where the problem comes in with yours (my wife has same bike). Trying to find a battery system that will fit the old case and is plug n play is a big problem. A ping might fit, but thats a lot of money to spend. You cant fit a rack unless you fit a later motor mounting plate, so you could use a frog battery on the seat post.

As far as altering other things like controller etc, its a brushed motor so would end up fitting a kit. At the end of the day (as Flecc says) its a crap bike, so do as d8veh says

Thanks for your replies.the one thing I'd like to do is what d8veh suggests throw if off a cliff but with the person I bought it off strapped to it.
other than it looks like I'm stuck with a crap bike.I have seen a 48v kit on ebay which I thought I could use
the the bone shaker but with my knowledge of E bikes very limited to say the least it would be a waste of money.

If you're willing to risk it, upgrade to 36v. The guys on ES did it without any problems. All you need is one more 12v SLA the same as the other two - should cost £20 to£30. You have to open up the battery case to see what's inside. Find where the battery wires plug into the controller, pull one connector apart and wire the battery between the two wires you separated. The battery has to be the right way round otherwise you get 12v instead of 36v and a lot of sparks/smoke. You can mount the additional battery on a rack or hang it in the frame triangle somehow.

This modification will give a lot more power and speed, but you have to be careful not to overload the motor by causing it to struggle under high load. You need to read that thread on ES carefully to see if a new controller is necessary for 36v. I don't believe it is, but there's a slight chance that you'll damage the controller, in which case a replacement is about £20 to £30.

If this mod does the business, you might want to think about a 36v lithium battery, which should easily fit in your case and save a lot of weight. I reckon that my 20aH one will fit in there. A 10aH one can be snagged for about £160.

It will probably be ok on 36 volts as d8veh says, this Currie motor system was originally a 20 mph one on both sides of the Atlantic until they started to comply with EU law more recently. Can't be absolutely certain though, since the motor/controller has been changed several times over the years. The original was a 900 watt beast which satisfied anyone's performance needs for the short time until it burned out, but currently the system has a 450 watts peak.

As Ive said what ever he gets he cant have a rear rack with out some serious mods to the rack. The battery case is a bit of an odd size, so he would need to find something else to fit behind the seat post.

The few extra volts you get from a lipo give a few more MPH but never checked that properly just by how much I can leave the wife by. You could get some 10ah headways in the case but nothing bigger but then whats the point of moving down from 12 ah

SLAs suffer much more from the Peukert effect than other types, so a smaller capacity lithium battery will give as much or more range than the 12 Ah SLAs. A seat stem mounted battery might possibly solve the problem of battery mounting elsewhere with the side mounted Currie motor.

setting a side your meanness (in good company on here) don't you love yourself a little...

A cheap but decent bike can be sourced from ebay/gumtree, strap you kit on that and it will bring much more satisfaction...

Thanks a lot guys for your help.and eddie for being a tight wad to.
I see there is a lot ups and downs with your suggestions its just figuring out which would be easiest for my inadequate brain.
I have just been talking to a seller on ebay who is selling a 48v kit and he said it would be ok to use on my bone shaker as long as I got a 48v battery, he is asking for a nose bleeding £200
what do you think.?

Thanks.I do want speed but as much as that bike looks great and has everything I would like the money is way beyond my means.I tried to sell the bike on ebay the other week and the most I was offered was £80 I only paid £120 about 5 weeks ago to get the battery reconditioned from a place on ebay that does them.
Thats why I thought the kit I mentioned maybe a good alternative.

Then best play close attention to whatever d8veh, flecc (and others) advise you. They have a lot of knowledge. I'm sure they'll be along soon enough to answer your last question. Good luck!

You've confused me a bit when you mentioned battery re-conditioning. You don't need to pay for that service: You just open up the case; unclip the old ones; replace with the same type.
Assuming that your batteries are OK, your options for increasing speed are:

Add another battery - cost about £30 and will give significantly more speed and power.

Change the sprocket on the wheel to one with lesss teeth- cost £10 to £20, but you need to some spanner work and grinding. It will give about 20% extra speed and a bit more power.

Chuck your batteries and get a 36v lithium one for about £160. A good option if yor present batteries are knackered.

Take off the motor and make some brackets to convert it to a crank drive like Geofft did:
http://www.pedelecs.co.uk/forum/introduce-yourself/12953-hi-warfield-berks.html. You need a free-wheeling crank that cost about £40 or make your own like Geff did.

I don't think buying a kit for £200 plus a new 48v battery is worth it. You might as well buy a new bike. A Bafang BPM kit and a decent 36v battery will cost about £450 from BMSBattery. You can fit it to any bike out of a skip and it'll go as fast as you want and climb any hill.

A lot of these things depend on how good you are at DIY. DIY brings the cost down. You can even make your own batteries out of recycled laptop batteries if you want to put some time in and are capable of understanding electrics. Naturally, the more you pay, the more you get - up to a point. You don't get something for nothing unless you're very lucky.

Thanks for all the info d8veh.as for the battery I paid £120 to get re conditioned from a guy on ebay
that was the IZIP CB26 one which I only got done about 6 weeks ago.but it only lasted me half a mile then needed charging.
you mention un clipping the case to replace the batterys.where would I get those batterys from please.as it would be an easy alternative to the problem.as I'm not very good with bikes and electrics
as I would probably end up with a bike doing 25mph backwards

First, you have to open up the case. It looks like it's screwed together. Inside are two standard SLA batteries that you can buy from several places. You need the size to get an exact match. that's why you need to open the case.
