Best ebike conversion

I actually bought two at the same time. Wanted to use them on our folding bikes that fit in our hatchback.
Here’s a picture of the other one.
Now that is too much. These were bought NEW? I'd certainly contact them and see what they have to say.

Yes, new The first one froze late May while we were traveling. My wife’s of course :-(
3 months out of warranty. She only had about 57 miles on it.
E-Switchy is hiding behind warranty. I’ve been emailing with them since June. They did offer to send replacement parts at a discount. I’m not willing to pay more for what seems to be bad quality control. I did like the kit while it worked! But that cost me about $10 per mile of use.
My wife’s controller.

Check out my E-Switchy! I got the biggest battery the S3. Had it for 4 years now with about 2,800 miles on the original motor and battery. @WhatsNext you must’ve left yours soaking in a bathtub, sir . I ride mine in the dirt all the time, and yeah… I’ve even pressure-washed it (even though you’re not supposed to). Still runs like new. Honestly, one of the best products I’ve ever owned.

I have attached two photos of one of our tandems – a Sun “Brikell” tandem that appears to have a frame identical to yours. As you can see, I have modified the captain’s seat post in order to bring the nose of the saddle over the bottom bracket. This provides me with a great deal more control of the bike at very slow speeds. The somewhat “feet forward” design of this frame appears to be intended to give both riders the ability to place both feet on the ground while seated on their saddles, but it makes the bike handle in a dangerously cumbersome manner at low speeds and is extremely inefficient for delivering power to the pedals, hence seat post mod and the electric motor.

In the second photo, you can see that I have replaced the rear wheel with one mounting a much more robust tire and a direct drive hub motor. As you see, the 48V battery is mounted in a carrier in the luggage rack. Mounting the battery in this manner will, in theory, create handling issues, but hasn’t presented any problems in our experience. Because the bike is a tandem – a heavy and cumbersome one at that, we don’t find the high center of gravity to be any more of an issue with the battery installed than we did before the bike was electrified. Not surprisingly, we enjoy our rides far more with the electric assist. Riding the tandem seems more like fun and less like work these days.

I have installed hub drive kits provided by Grin Technologies, E-Bike Kit, and Ebikeling and mid drive kits sold by Electrify Bike. I have found all of these vendors to be most helpful in supporting their products.

I love my E-Switchy kit! Since I have the pedals attached to the front wheel i installed the kit onto my rear wheel! Works incredible, I got the Switch Three model with highest range. Excellent support by far from all other companies I dealt with. E-Switchy is really setting the bar. Had couple of parts that needed replacing (my fault) I was still under warranty and they just sent me replacements right away. Very happy customer :)
