Maintenance free bike (project)

[cwah]

Hello all,

I decided to go on a maintenance free bike as the previous thread started. I received the BBS 02 and the battery:

Problem are:
- Dual suspension makes the battery rack bounce out. I need to change the seat I think?
- The chain is slipping under load. I'm thinking I need to change the gears?

What tool shall I use to change the gear and put one that doesn't slip under load? And maybe also one nice chain?

Thanks

Try a new chain first. The chain needs to be the correct one for however many gears you've got. The chain won't slip so much if you start off in a low gear. You also need to get the gears properly set up with correct end-stop adjustment and cable adjustment. Also, it might slip less if you fully tighten the tension adjuster screw on the back.

That rack cannot be fixed to the back of the bike or else it will shake to bits. That's the wrong type of bike for that battery. It'll never be maintenance free. The weight is too much for its rack. If yo want to continue with it, it has to be fixed to only the rear sub-frame like this one. Your photo is not good enough to see your bike, but as far as I can see, it's going to be very difficult to fit a rack to your sub-frame - or to fit the battery anywhere else. You have to choose the correct type of frame to fit a large 48v battery to:

The chain is completely new and is still slipping. I was thinking to change it to a new gear so I'd have it all new but I don't know what tool to use?


Do you have any idea? Is it a cassette type?


I bought the battery for quite a lot, isn't there a way to use it in this bike? Maybe I should just get an old dutch bike for that?

You need a cassette removal tool. Rack batteries are difficult to fit to full-suspension bikes. Your bike doesn't have any space in the triangle either, so it won't be easy.

The tools are OK. For a cassette, you need to get one with the same number of gears. Any one will do, but generally, the more they cost, the better they are.

Thanks understood. will get them and put new gears on it. Maybe a new bike but I'm a bit annoyed to have to sell this one and get another one..

You need a hard-tail for that battery. Even then, I guarantee that the welds will break underneath the battery, so that there's nothing to hold it up. I think I'd chuck that rack and make/get something steel to mount the battery to,

My Dillenger rack collapsed within a week of fitting it to a hardtail with the rear supports.
Previously on the suspension Trax bike it was fine just supported at the seatpost.

I paid so much for this battery + rack:

Almost 300GBP. Do I need to bin that out although it's almost new????

The battery's probably OK, but the rack design is crappy. If you want maintenance/breakdown free, you have to make a steel one.

When you decide on a new bike conversion, you have to plan everything out in your head before you get the bike or kit. If you get the stuff first, it's much harder.
