My in-laws are in the 80's with balance issues, I bought them a Lectric XP Trike for $1500, they've been able to enjoy it as much as the fat tire e-bike they used to have before the pandemic, when they had less balancing issues.
The problem with a trike is that I live in an apartment with no place to secure it, otherwise I would already have one.

I have yet to be able to stabily launch the bike by peddling it from a standstill, so I believe that this can only be done with assistance from the motor.

Try not to be so arrogant in your assumptions.

And FYI - you could post a picture of the "ebike" in question, and see if someone could find a solution. Get a new battery/controller/display combo, if applicable. The battery doesn't necessarily have to remain rack mounted.

If you believe that I have wasted your time, why are you still doing so?

The bike is a 2017 Raleigh Retroglide iE (stepover). I would have to rewire the whole setup to mount a different battery to the frame.

Between the canbus system and the integrated controller of the Currie motor, they made a mess of it.

As it stands, I suffer from brain cancer, and can only attempt to ride when I am feeling up to it, and I may be waisting my time with this particular bike.

I however want to press on to see this project thru.

I'm wasting my time because people help each other out here in the forums. That's what we're here for. And I'm sorry to hear about your cancer. That could also affect your equilibrium. Here's a picture of your ebike. Looks like it's mod'able, but it might be too cost prohibitive.


PS - mid drive? If you can get it up and running, it will be worth it.

I only need a new inner battery pack to make it work. If I can find someone to build it with LiFePO4 batteries, and a good BMS, even better.

You'll get a bit more assistance in this section. Hopefully someone can recommend a solution. Please be patient.

EBikeMarketplace in Las Vegas is a company that reportedly (I've never used them) rebuilds batteries. However, mailing yours to them is a conundrum if it's even something they can repair. I would think that, since you reside in a metro area (from your location), you should be able to locate a similar service nearby. It's possible that a new battery can be combined with your Raliegh interface or since it seems like there may be positive and negative wires going to the controller, just splice in a different battery. If your bike doesn't have a throttle, you might take a look at a new Electra (flat feet technology and sold at Trek stores) if it has a throttle since that would facilitate starting out. As stated above, I'm so sorry to learn of your affliction and the more information we have (especially budgetary), the more assistance we can provide.

EBikeMarketplace is pretty flakey these days, and their price is more than I would like to pay, especially with shipping added in.

I would like to stay under $500. I was planning to contact a few Chinese battery manufacturers to see what they can do for me. But you never know what you will be getting from them.

The wires from your battery to what I assume (I know, I know) to be the controller APPEAR to have positive and negatives. If so, you could hook up a battery which had for instance an XT-90 "female" connector by splicing an XT-90 male (probably with pigtails) to those wires. I would concur not to use a Chinese company. Also, for only $800 you could procure a Lectric Cycle ebike with throttle (although only single speed); maybe you could defer part of the extra cost by selling your bike for $100 - $200.

I paid $200 for it just a couple of months ago. I have looked at all of the affordable ebikes, and they all have one thing in common. Cheap parts, and indifferent quality and engineering.

If I can't get the one I have going, I will give up on 2-wheeled ebikes entirely.

Saw a survey that most of the accidents among the elderly riders are from mounting and dismounting when stopping on a bike. A crank forward design (also called cruiser, feet forward etc) maybe the way to go. A recumbent bike is on the extreme, but you can go with the Electra Townie where the bottom bracket is positioned about 6 inches front of the seat tube. This design allows you to stop without dismounting from the saddle. You can find them used on craigslist for under $300.
If you can bike wrench, buy a mid drive kit and build yourself a decent ebike.
I suffer from some back pain so I got a used $300 recumbent. Another $300 for a Tongsheng mid drive kit fr aliexpress and repurposed a 48v server batter for under a hundred.

Rebuilding a battery pack ain't rocket surgery. find a local tool battery guy and pay him to look at it so it's not a waste of his time if you don't fix it.
But you want to know what cells it's using. Are they flat, Samsung style, potted? Specific output per cell. cell id numbers if possible.
Cells, unless custom, can be sourced. The beauty of the whole chinese set up is they all use the same commodity parts so almost nothing is super custom.
And if, when it's open and he says "Oh these are XXXX" ask him to fix it.
You're not going to be changing battery types unless you know someone that can built you a control circuit for your new set up.

Hi George,

A couple ideas:
  1. There's a woman on facebook named Susie Cen who can source new battery packs directly from the China suppliers. You might try reaching out to her with some pix and specs of your battery pack. I bet she can do a lot better than $600.
  2. Maybe you shouldn't give up on a trike so easily? You could just invest in a quality lock, alarm and cover and lock it up outside somewhere
Good luck.

I have decided that a trike would be best for me. Thanks for your help.

Why do people post stuff like this?

If you lived closer I would help you modify the bike to use a generic battery.

I helped a friend try and find a bike for her son with a balance problem. Lots of good options for a trike but hear you on the issues with storing and transporting them. He ended up getting an electric scooter, he could balance that.

BTW if you have trouble starting out on a regular bike don't even consider a 2 wheel recumbent. Those are tricky to get started.

Bicycle stability is a complex topic, but I don't think that is your issue. My guess is you have trouble starting out due to the overall weight of the bike and possibly from trying to start out is too high of a gear.

As for your battery at some point it connects to the controller with two wires. What you may need to do is install a connector allowing you to use a generic style battery. Batteries can be mounted anywhere on the bike, even carried in a backpack with a long power lead.

No shame if you aren't comfortable performing such a modification, but perhaps you know someone handy enough to help you out?

Some bikes use proprietary batteries, sort of like an Apple product that won't work unless you have an Apple approved charger. My guess is your bike is not that type.
Wrong person to quote. I'm not the person having issues starting out riding my ebikes without power. Please go read the prior posts. The OP has health issues (cancer).

I did post that comment, but it was before we had additional information added. The OP, as you see, has special issues. Hopefully it's working out well for them. This ended up being a bit more involved than just simply get basics and providing a solution.
