    I cannot find spot weld professionals!

    Yes I know the Samsung 22P but they are definitely not as good as other (such as the konion ones) for the same price. I've found a supplier for some experimental cells for very decent price 2USD/cell with 5C discharge capacity and 2.2AH (with 2AH true capacity). It's quite good for the price...

    Dahon Jetstream conversion

    Hech, on this bike I'm using Zippy compact with a pack at 72V20AH. In term of sag I only have 3V drop on full power at 2.5KW. So about 0.15V drop/cell on max power... Quite good but my pack is big :) My brompton had these very nice konion. They were good too but had much more sag and were...

    I cannot find spot weld professionals!

    I have a spot welder at home (in paris). I can help on that. Check what I've done before: i'm looking for someone to buy cells together and share shipping cost. Do you already have the cells or have a supplier in mind?

    Exiting New Things

    Aaaah... I wanted to buy it but didn't because I'd use too much power... But just tell me it has more torque than the BPM and I'll buy 2 of them for a nice dual drive at 3KW :)

    Compact tandem

    There's no way I'd ever get the Donkey bike. It's not suitable to carry a passenger and it's too wheelie prone. Same for your Tandem John, there is an obvious fault on this bike and battery rack on seat post has never worked for more than several months. They do NOT withstand bike vibrations. I...

    Compact tandem

    The rear or fronr racks are definitely strong enough to carry a passenger. And due to the geometry I can see it quite wheelie prone.. The cannondale looks to be a better contender!

    Compact tandem

    Yeah that's why a small cargo bike would probably work better. I don't know the exact size of the lift (I don't have any rulee here in london) but it wouldn't be much bigger than a normal full size bike. I'm planning to put 15kg of battery and 2 motors on it so I don't want to lift it lol

    Compact tandem

    John, I was thinking of another type of tandem than the one shown. I don't think I'd be able to fold the bike quick enough for daily use. Also, this tandem battery support is never going to last a year. I was thinking of a proper compact one such as all the other one shown here. I can wait...

    Compact tandem

    Geebee, juice bikes are nice but waaaay too expensive. 3000USD as initial cost and I'll have to add probably 1500GBP more to customize it to my needs... I can't afford that much!! John, if you manage to show me something that fits in the lift within 5 second I'll buy it lol. Lift is about the...
