Not sure about an e bike, but in at least 15 years I've never needed more than this multi-tool for MTB and road biking. I've patched many flats, made every adjustment, repaired muiltiple chains with it. All I've ever modified on it is the heat shrink on the hex adapter so it wouldn't slide down and posibble get lost. Never needed more leverage or apply more torque than it's shortness would deliver. A kit you carry is for emergency repairs or occasional adjustments.
My kit includes:
- A patch kit with a piece of leather in there too in case I need a boot, extra Presta adapter too..
- Rubber gloves, for chain or greasy work.
- Chain links and some garden wire to hold the chain in place for repair or whatever.
- I got sick of breaking or losing pump parts, so I've switched to CO2 instead of a pump. I've yet to use it.
- There's a tire spoon on the multi but I also carry and extra to have two.
- Of course there are a few zipties tucked in my bag.
I keep all the tools in the grey glasses case. The other green glasses case has a pair of yellow polorized night glasses for riding when it's cloudy or at dusk, I just switch my sunglasses out with them. Both those cases fit quick and easily in my saddle bag. Yeah it's big and heavy, but I'm no 'weight weenie'. My easy to grab Presta adapter is hanging there too.
Sorry for the partial thread hijack... LOL ...But the title is great to expand on.
