Most modern day EPAC's are far far better then 15 years ago as are the kits for diyer's. Range doesn't need to be an issue, over 100 miles is quite easy today with better cells available. As for disabilities or mobility issues a Wisper bike with a legal SVA authourised thumb speed control...

If one searches the 'Search' part of the forum there is likely someone who has replaced them. As long as the motor connector is a julet type then there should be no issue. That controller you show is too powerful , you will need a 6 mosfet 15 or 17a controller and not a 30a model. One will need...

I go 32t /42t on a twin chainring set up, with mid drive kits 32t is the smallest one can get away with. The front mech also acts as a chain keeper. My hub bikes are much the same as well, like Benjamin I'm not and overly strong on the pedals and my av cadence is high 60's to mid 70's.

Certainly that hub has an issue with moisture ingress , not surprised it was noisy.

Another moped review , the bike is a moped 22mph and 500w rated motor.

The forum is about EAPC legal 250w assisted bikes so likely not much interest for EV's on here that don't conform.

Some people just don't get it . The concession for EAPC's is that they are limited in power and how that power is activated, to be as near as possible to a non assisted push bike . If folks think they can out put more power then a 250w EAPC then they don't need an EAPC. If one wants a moped...

Used spare parts or another used GTech is likely the only reliable source for spares. Tbh though the cheapest and best option is to buy and fit a KT controller and display , then all you have to decide is what volatge to run at 36 or 48v. Check the motor cable connection is standard type 8 or...

One can't know exactly what has occurred without someone opening the battery and carrying out some fault finding , but an unbalanced /low cell group is likely . One thing you haven't told us yet is the discharge voltage reading as this can give a clue to whether it is BMS related or a balance...

I find with the 5.5mm charge jacks it is easier to buy a cheap counter part to plug in and then probe the contacts . The speaker Green type uses screws contacts to attach wires so one can simply probe the screws.

Controller mosfets act in the way you describe, they will temporaryily short out once thye get too hot. Riding too slowly up gradients will produce the effect. Tell tale sign of the mosfets cutting out is the controller is as hot to handle as a hot spud.

Likely out of balance .

KT TS control systems are rare on the open market , some years ago BMSBattery were selling KT TS controller kits. Typically though I would say a standard KT LCD won't wotk with aTS controller.

KT cater for the non OEM market for kit bikes as well as OEM bikes for brands. They also offer custom systems for OEM brands so the programming and software will differ from standard non OEM systems . As an OEM system is doesn't go cap in hand that one can just buy any KT part. We have see this...

It's not often we see OEM bikes with KT systems so the system may be a KT custom job as it only uses a three mode lcd, this likely means a standard KT display won't work with the controller soft ware. Non custom KT displays are for five level PAS systems . The pictures aren't very clear if...

If I have to talk to people that I coming upon them , then I would have to shout out from a distance. A ting ting bell from a distance can usually be discreetly heard unless they have their face stuck in a phone or wear ear phones. I ping the bell three to four times from afar then a couple...

The kit can never comply with UK law, the hub is rated for 1000w . The so called 250w rating is a red herring to try and diguise the fact and trying to circumnavigate the law. Sadly these kits dupe the buyer and the companies selling them know this but turn a blind eye to the law. Unless the...

A nice gift to be given to make a project of it K .

Much the same as the dearer Keyde offerings , one has to wonder how reliable the inner controller will be in such a small space as well as the heat retension. 280rpm is the only speed offering at least the Keyde offering has three rpm offerings. Are you going to be the forum guinea pig on...

One now has to find out why the chain threw off to the inside. Is it worn ? Are the chain wheel teeth worn ? If any of these then it will occur again. For chain wear /stretch accurately measure ten links pin to pin center, anything more then 256mm then the chain needs replacing, if one...
