Help! Wiring new controller
- Thread starter collibl02
- Start date
If that's from your Carrera Impel 2 with the Hyena controller, it'll be as Nealh suggests - comms of some sort. There's no standard between systems so it could be anything. On some there're things like temp sensor, low voltage tap for bike lighting, digital feed for battery/range display.
yeah it’s for the IMPEL2, but it seems that when I connect everything back up I’m getting no power unless the other four cables are connected as well but on most 3rd party controllers there is nothing to connect too.
I’m thinking if I connect the red and black to spare red and black on controller we should see power but that doesn’t seem to work I need to connect the blue and yellow to something as well !!
Then it's most likely tx/rx/CANbus/UART comms where everything talks to everything and if those comms aren't present in the form it expects at best it'll throw an error code and at worst nothing works. Welcome to the world of closed systems just like Bosch, Yamaha, Brose et al.
On my own TranzX "closed" CANbus system (where I have the Dealer software so can "read" the bike) it appears you even have part pairing and a payload file; it knows what parts should be there by logging serial numbers of the components. Should you dare to change a component even like-for-like, you need to update the software creating a new payload file in the process. It stops DIY-ers fiddling and limits diagnosis and component changes to the Dealer network.

The more the brands that use Canbus /handshaking with EAPC's , then the sooner they will end up as scrap or landfill.
Not good for the environment is it, though the bike can become a handy trellis for growing your peas? I use these bags with my old bikes:

There's no reason why the manufacturer couldn't make these diagnostic systems available to the end users... other than it's protecting the business of the resellers/dealers. All the bike-owner needs is a laptop/tablet and a cable to diagnose and repair their own bikes.
Bafang's latest CANbus BESST software is (reportedly) available to the end user (albeit about £100), and there are reports that the OP's Hyena system has software available too? TranzX's isn't officially available, but it pops up on the web to download and install from time to time as few UK dealers now support that system (since Ebco threw in the towel). That should happen more...
"Closed" system bike-life could easily be extended if the owner could effectively fix their own bike more cost-effectively by not having to pay a dealer, and that's exactly what these systems do best - make problem diagnosis both very quick and idiot proof by telling the bike owner exactly where to look, what to check, or worst case what's failed and needs to be replaced.
In this sense, UART/CANbus closed systems could be considered ideal for lesser knowledgeable people to keep their bikes running... more so than one using generic parts where knowledgeable folk like those found here on this (and other) forum(s) are often needed/invaluable.
The bigger issue as I see it is the increasing unavailability of specialist parts as many of the earlier systems stop being supported (Soundwave's comments re older Bosch, Daum, Panasonic, and certainly some TranzX components now - Yamaha/Brose/Fazua et al I have no idea). As with most reputable domestic appliances, there's no reason why parts shouldn't by law be made available for at least 10 years before being pronounced obsolete... don't Wisper and Woosh both do that? Has even an e-bike using generic Chinese parts really got much of a life beyond 10 years?
As I see it, with more and more e-bikes (even cheap ones) now coming equipped with Bluetooth 'phone apps for rider stats/tweaking performance, including a system diagnosis element would be/should be a piece of cake... except that doesn't protect a Dealer/Retailers ongoing business, does it?
It's is simple , the brands with closed systems don't want you to repair /fix yourbike, let alone diagnose the fault. There is no money in it for them, that is reason enough.
That is reason enough why many wouldn't buy one.
But the point is more might if they had some control over their e-bike's longer term viability in terms of fixing it and keeping it running themselves... without resorting to kit-bikes and lower level imports with generic parts.
I think the Far-Eastern Direct Sellers may well wake up to that possibility before the Europeans do and they find their hands forced.
Even so, the OP's bike isn't going to go any faster (dongles and other cheats aside)... even with these diagnostic systems (Bosch and TranzX ones anyway), the maximum assisted speed is resolutely hard-coded within. On that point, I notice with increased frequency members here finding both ready-made e-bikes that do use generic parts and kits too locked down in terms of speed and throttle/walk assist. I'm sure that's reason enough for some to avoid buying those too?
I suspect the companies are having to make some sort of risk judgement on legal liability / potential reputational damage for their bikes that have been de-restricted - maybe we should be pushing for looking at the regulations around L1e-A and L1e-B bike classes and coming up with a suitable regulation framework
