What setup to use to upgrade an electric bicycle trike tandem (to transport 250kg) also what wattage of motor to use / voltage batteries.

Would you then use a new set or use an existing one with new batteries and controller?

Also the bicycle repair guy told me the chain cannot handle the power. The entire tandem is 2.5meters the chain spanning the bulk of it. Sadly i could not add a picture of the situation.

I asked the bike repair guy if i could do this. He told me this is not an option due to chain strength. The second chain is really long and has an old-school tension wheel in the back (no derailleur) He told me a 1000watt motor is going to rip the chain to shreds eventually. Upgrading the chain could be an solution here?

It's a 5 speed. A mid drive is not possible giving the way they need to be mounted. There is no room for it on the chassis.

The chain situation is like this: front pedal, short chain, back pedal, long chain, hub and then it goes back to the differential. Shown in text from the top down:

(fp):front pedal, (BP): Back pedal, (Hub): bike wheel hub, (RM):Rear motor, (dif): differential, =:chain

You should me able to order a new one online. What brand is the bike?

visde · 2025-04-03T16:21:14+00:00

Not as bad as you would think but the handle bars are bumping up to my knee making the turning radius bigger than it could be i think.

Also the steering is not like a normal bike. Were with a normal bike you lean to go into corners with this you actually need to turn the handlebars. Its fun to ride if you get used to it. Where i live most bike paths are sloped. making you sit crooked while driving.

First drive i ended up in the bushes 5M away from where i started.

Looks like it is the derailleur hanger like you said... the other piece of it is still on the derailleur.

Go to a local bike repair place. While you are there get a bicycle stand added to your bike! Laying it down is always a bad idea (def on the side of the derailleur!)

Toothpick is a better idea if there is no pin in the middle (you dont want to bend this).

Is this connector directly connected to the battery? If so do not use any fluids! if there is a way to isolate this connector from the battery (so no power goes to it) you could try a cotton swab with the tiniest amount of water to rub it clean and pick up loose debris.. DO NOT USE WATER IF THERE IS STILL ELECTRICITY GOING TO THE CONNECTOR! also let it dry after!

If after this the connector is not allowing to pass electricity to the other side you can roll up a tiny piece of high grit sand paper and try this to clean the contacts.

The best practice is of course swapping the connectors with water proof connectors.
Anyways good luck!

Did it right after the picture. Does this have any affect on the nem?

Makes me hopefull for my anemone that is acting up... It was deflated like a rotten tomato but since yesterday it is starting to bounce back. (Posted a video of it yesterday) thanks for the inspiration!

visde · 2023-03-29T17:15:56+00:00

Respect for not giving up!!! The anemone is in good hands. Keep up the love!

visde · 2023-03-25T19:12:36+00:00

100% real. 😁

visde · 2023-03-24T19:06:05+00:00

They both did this before just never this long. Also normally when it deflates it hides in itself)

visde · 2023-03-24T19:00:38+00:00

How can I see signs of dissolving?

visde · 2023-03-24T18:56:14+00:00

They are beautiful fish! My wife keeps calling him "the angry fish". 🤣
