Just because it says 1000w doesn't mean it will be better. Often most grizzle about lack of range because they are sold a battery that is able to supply enough power for a long duration. Most think they van get away with the cheap kits simply on price vs a more expensive legal kit that is far...

Why does every one come on here and want an illegal moped, any 250w pedelec will be as good as a moped you talk of if use din high power mode. It will out put approx 400 - 600w of powerand some like bosh & yam output 700 - 800w.

Not unless is has msva approval, then it becomes an Lpm /moped that has the same right as a pedelec.

Once fully charged it can't charge more then 100% or what ever the BMS deems as full, so the charge will cease. Simply use a wall timer or traipse outside to disconnect it, after all going outside to the out building isn't exactly an onerous task. Leaving it on charge constantly can and does...

Show us some pics, we can't view a blank screen.

Like any bike a folder is good if it suits yours needs, I see no benefit in saying they aren't good this or aren't good that etc,etc. If the need for a bike is too be able to carry them upstairs, on public transport or pop in to a vehicle boot then they are ideal and practical.

The smallest chain wheel for a BBS I think is 32t using an adapter spider.

It will work with lithium without issue though the controller specs would need checking as to max voltage,

The hub is likely I believe an old brushed type one can confirm this as it will have either one or two pairs of phase wires. It isn't to dissimilar to the sakura mid motor design of bike. Flecc will likely have more info on this older style early ebike.

Range has to be put in to context, the published figures will be done using a super fit rider on a flat course with no wind or rain. They will of course be riding above the 25km/h speed limit so actual assisted constant figure won't be a real world 62 miles.

The close up pics of all the Tern failures seem to indicate a poor welding process of the hinge to the frames, esp with the weld depth barely looking like it has penetrated enough. Most of their welding was out sourced all over the place so QC was very poor.

David Hon is still alive and still Dahon ceo.

One will need to go OSF route to tinker with the settings to make them more distinguishable, it may be that the TS isn't set up very well or the controller parameters are too much alike. Experiences with Open Source Firmware on the Tongsheng TSDZ2 | Pedelecs - Electric Bike Community If you...

It will end up looking like S**t just like this one but minus the oversize boxes. What a machine!! | Pedelecs - Electric Bike Community The joker on ebay was asking 4.5k then it went to 8.5k, there are some dangerous people out there .

The cost and hassle won't be worth the effort. Next you will find insuring it will cost 'HOW MUCH' and more expensive then a 1000cc motor bike.

David Hon /Dahon bikes are safe and have a good welded hinge design, when the acrimonious split occurred with his then wife and a son they jumped ship. Apparently taking some of the company designs to form Tern bikes, one bit of the design they didn't manage to take apparently was the hinge fold...

62 miles from 248wh one would have to be consuming 4 wh/m to achieve that and certainly above the cut off limit nearly all the time. The app is assuming a modest 10wh/m which is about average usage for a regular rider, an everyday rider or above average rider who is ride fit should manage low 6...

Not all batteries charge to 100%, it depends on the default BMS top end balancing. I have one that stops charging and balances to 4.15v per cell, doing so preserves the battery life cycle a little longer.

Cheap partly because of the crappy 3 spd, speed control system used as well as general cheap bike components. The hub and battery will account for some 60 -70% of the bike cost so that should tell you a bit about the mechanical parts used.

Anotherkiwi who is a member but no longer posts as he is now on a German velo forum, he used a KT ext controller and PAS on his GSM after it failed. So it may be a controller fault, I suspect it is more then likely a mosfets issue with heat.
