Best ebike conversion

[Larryo]

Hi,
Looking for a better conversion. I currently have an electric Daymak tandem. It started out as an electric bike, but the system failed and rather than fix it, I had my bike mechanic install a conversion kit. He put in the ebikeling S830 which has worked OK. Has some quirks but overall a good system. The display failed and getting support is a real pain. They won't give out a phone number, but instead use email, which takes MUCH longer and still waiting for a few simple answers. I just hate poor customer service.
My system has a 48v battery, 15amp, which takes us over 50 miles. The motor is on the front wheel model CENC22FVE0091, which is plenty good for my slow speeds (but will get up to 28mph top end). The controller is a DC moto Controller.

I'm fairly new to ebike, so bear with me.

Are many of the parts interchangable? Like batteries with the same connections? I'd like to keep my battery but upgrade the display/controller if possible. Or if not available, get a whole new system. Reliability is most important as I venture into very remote places.

Thanks for the replies.

I don’t know the answers to your questions, although I think you could probably use your battery with a different motor.
as for the controller, you might want to talk with someone who’s in the business of building e-bikes.

I’ve had good experience with the electrify bike company. You can call them for a consultation. They build bikes and sell components. And they have a lot of good information on their site. Good luck.

For power connectors, don't worry about what sorts of plugs the factory uses, they are all trash. Go down to your local hardware and buy a pack of male/female spade disconnects. Put some Oxguard on the contacts, it makes inserting them and later disconnecting easier and also guards against corrosion and adds a bit of extra weather-proofing. Then if you want you can seal the reverse ends with liquid electrical tape. Doing this prevents shorts, since the wires each have their own plug. These plugs are rated for higher voltage, higher amps, they are cheap and easy to replace, and they protect your battery better since it's nearly impossible to short out.

You are right, once you grasp the fundementals there is little esoteric about most components. I favor the KT series with DD motors for many reasons, was going to do a TDZ middrive on my current build the Bottom bracket was so wacky I went with motor wheel instead.

Just converted my tandem bike into an e-bike using the E-Switchy Switch Three model (battery mounted under the forward seat), and I couldn't be happier with how it turned out. I wasn’t sure how well it would work with a tandem, but the installation was surprisingly easy, and the performance has exceeded my expectations.

The motor handles two riders effortlessly, even with my heavy tool bag on the rear rack. Hills that used to slow us down are no longer an issue, it just powers right up. The battery life is incredible; we go on long rides, and it barely seems to drain. My wife and I ride a few miles, and the battery still looks almost full!

One of the best parts is that I didn’t have to buy a whole new e-bike. I got to keep my tandem and just upgrade it with electric power. Having both pedal assist and throttle control is included and makes a huge difference, it gives you flexibility depending on how you feel.

Also, I have to mention E-Switchy’s customer service, it’s seriously the best I’ve ever dealt with. If you’re thinking about converting your bike, I highly recommend giving them a try.

Cycleman,
Thx for the reply, Since my first message, I lost my tandem to the Helene flood (in Florida), so I'm starting over again. I like the idea of converting a bike, because it's much more reasonable and there's a lot of good non E tandems out there. The E-Switchy looks great!

PS, I also have a 3 wheeler "surey" for around the neighborhood, which I'm thinking of converting, using some of the components off the bike I lost.... we'll see. Then I can take much longer rides without worry about getting home if tired of fighting wind or hills.

Sorry to hear about your tandem, losing a bike like that is tough. I recently converted my bike with E-Switchy, and it’s been awesome. It’s super easy to install, and the boost makes a huge difference, especially on long rides or when dealing with wind and hills.

Your 3-wheeler surrey sounds like a perfect candidate for conversion! Having that extra assist will definitely make cruising around the neighborhood and longer rides much more enjoyable. Hope you get back on the road soon!

Thx for the ideas. Yes, I miss my old tandem, but it served me well over the years, with two trips to Canada by boat, having it with, made a huge difference on local transportation when docked.
I've kinda switched my goal after writing the above and now considering an E Cargo bike with the passenger option. There are several out there but Rad and Lectric both have very suitable options. The downside of the Cargo bike is the stoker gets no exercise, but just a ride. The upside is they are very reasonable, smaller for portability and have good reviews and specs. Thoughts
