It would be quite lightweight. About 130kg for 2 people I think. So it shouldn't break?

Hello all, I very often miss the ability to carry passenger when I go out... not fun when other are taking the tube while I cycle out.... I thought about this: Weld another tube to the seat tube and add a motorbike seat to the bike. What do you think?

Are you plannning to mount it to the brompton? :)

yes, I'd like to do that but to match frame curve I'd need to do some molding. I'll have to think about it but not sure it'll be a solution. for the secobd point, can you give example of waterproof cloth? something like 600D fabric?

not sure how it would work. It's a folding bike so anything on the rear would become a hindrance to the fold

If it's 29.4V 2A I have a spare charger with this exact value: I can ship it to you for 10GBP as I don't need it

Jerry yes I have 2 brompton. 1 with mini-DD and other one with the mac. But mac motor is down so I'm using my spare brompton I do not want to always have a backpack, it would be really annoying. :/ And yes, many people told me it wasn't so pretty on the frame.... and prefered the version on...

I'd like to find idea maybe to wrap it clean? I'm using vinyl carbon fiber for the battery box, but for the triangle part (with controller and 12V adapter) I'd need some sort of cover. Carbon fiber would be too weak on this area... anything to cover this part without having it torned down...

splitting it is no problem. Problem is where do these pieces fit on the bike?

I moved it out of the bag for better handling. Bike is much more stable now, especially when I go a bit faster. I really don't want to move it back to the brompton front bag.

ahah thankss but I don't think it's going to work lol

you need to check connectors. Do you have pictures of the connectors you are using?

hello all, Before I had my brompton battery on the front bag: Comments were: "wow, is it an electric bike??" "where is the motor? I can't believe you pedal so fast" Now it is on the frame: and the comments are: "look, an electric bike?" "ohh a folded electric bike" "how much does it...

I'm now only considering cylindrical cells for their flexibility. I can shape them to the bike form factor, get the exact capacity I need and I KNOW what are the cells used in the pack as I've tested them. I'd only consider bottle or ready made battery pack if I seriously lack time. The...

aaaah... ok lol I don't think anyone would care in France. lol Never been checked on my bike "legality" :)

I don't see your point mike

hmm... ok sorry I misread. too bad nothing decent exist currently.

can you give us a link to your tracker? i'm interested if it works in france

there is a little slider where you can adjust the amount of "throttle" (or pedalling) you would use. Just have a play around and see how many AH you need. Ultimately, if you're a good enough cyclist, you don't need any AH :rolleyes: ps: I never used any bottle battery so can't advise on it

I think your main budget will be on the battery. You can check on the simulator to estimate how much you would need: ebikes.ca Hub Motor and Ebike Simulator Compare either a BPM36V500W or EzeeV2(26") motor and a 36V20AH battery. You'll see you can achieve about 32 miles distance no pedaling at...
