The lowest we were quoted was around £600 ......here is the website of the people who made ours, they are supposedly a really good brand , the prices are on there , but the bike shops in Altinkum don't stock all their range

The problem with these bikes are that they are silent. Walking along the front and the pavements are a nightmare, they are behind you and without you knowing, its quite a shock when they pass you.
As per say, the Turkish drivers go as fast as they can, I see a big accident pretty soon.

I was just thinking of the battery problem when not being used for long periods.

How about putting the battery on the charger, that would then be plugged into a '7 day' timer (monthly would be better, but have never seen a monthly timer), with it set to turn on for maybe just 15 minutes once a week just to keep it energised.
Obviously due to power cuts a mechanical timer would be better than the electronic type as they sometimes lose their settings during a power cut, and at least with the mechanical timer it would not matter that the actual time was incorrect.

We were told by the guy who we bought off, that to keep the battery running properly, you should treat it like a laptop battery....let it run right down THEN charge it up
As for them creeping up on you, yes I've had that problem before with bikes creeping up on me, but the one I have at least , makes a faint noise which is audible and if going where pedestrians are, I am very careful not creep up on people

I would google it to be sure on the type of battery. Others may know better but my understanding is:

If sealed acid type then it requires a trickle charge if not used.
If like laptop type Then some have a memory so require to be run down others it dont matter.

I am not up to date with the technology but I would google the battery type (serial number / make) to be sure, I don't trust anything they sell me in Turkey.

Just awakening this thread both to update some info but also to ask a question.

UPDATE:
On the battery charging problem I recently purchased a mobility scooter and was told even up-to 6 months providing it was fully charged and the had the battery disconnected it should not be a problem, although with some of the scooters and bikes it's only a matter of lifting the battery pack out of it's housing and not physically disconnecting the batteries, only apparently the problem is when the battery pack is still connected to the circuit as it is still constantly monitoring the system status which runs the battery down and once run down to zero charge should not be left any-more than 24 hours before being recharged because that is when the battery problems begin.

QUESTION:
What is the electric motors maximum wattage before it has to be registered.

NO with these type of batteries they should NEVER be run down until they are flat/dead as it harms the batteries. And likewise although most of the chargers automatically turn off and stop charging they should not be left connected for any length of time also but I was also advised against using the likes of 7 day timers were because of any possible surges/spikes in the electric supply.

Fully charge the battery before disconnecting the battery or battery pack and it should be ok for up-to 6 months, then put back on a overnight charge when ready to use again,
I am of course talking about the dry cell batteries as used in Mobility scooters and also electric 3 wheel trik's.

I have an electric car here in England and I keep it charged when ever I can get it free from the supermarkets that's most of the time but I have a 7 economy meter midnight to 7am half price charges that I use maybe once a week

Maybe should have posted earlier but got all the information I needed from over the road, plus downloaded manuals.

Sorry bringing up an old subject but my wife is finding it hard to walk as far so we were thinking of the Electric bikes but as you know the battery is a problem keeping it charged if you are just out for a few months is it possible to rent one and if so where would appreciate any feedback thanks Tom :D
