Assist vs pure

[jago25_98]

I just hired a German built electric only bike yesterday. Wow, a lot of fun. Very fast around town... Faster than anything i encountered... but also handled off road pretty well too. I can think if few things faster in the city. It goes up to 50km. The feeling of silently pulling away from the lights faster than performance cars is amazing.

The only thing I don't like is the range. It will only last enough to get to the next nearby town... And do this once in the day since the recharge is 4 hours. As a result a normal scooter makes more sense. It seems like a waste to have something for just around town...

The other option is electric assist. The best of this looks like the FlyKye to me, even with the drawback of non removable battery and speed limit. The only option lost here is not being able to leave a spare battery with someone halfway on the route somewhere.

But I'd miss the speed. Its hard to go back to a bicycle once you've used motorbike speeds.

I guess its apples vs oranges and maybe neither makes sense...

Maybe an ebike with quick swappable battery?
The thing about this bike is that its sturdy. So to make a diy system but with quick switchable battery might not compare. Perhaps a full suspension bike with road tyres maybe...

I wondered about taking a old ebike with a broken battery and trying to customise so that the battery is quick to swap... Then buying 2 new batteries. Has this been done before?

Hi - I think it's fair to say that the vast majority of pedal assist ebikes have detachable , and therefore swappable, batteries. Usually mounted in the frame like the Bosch system or on the rack

Some also go behind the seatpost requiring a longer frame which doesn't suit everyone

Take a look a kudos, juicy
woosh, ezee ranges and you'll see what I mean

Just buy a spare battery and away you go. Or put both on the bike and swap when the first runs down (one in the triangle and one on the rack for example)

The only thing to watch out for is if you are using a bike with a high power non road legal bike (250w nominal is the limit) some batteries may not give enough amps to run a beast of a motor

Have a look at BMS battery online also . There you can see a whole range of ebike kits and batteries to give you an idea of possibilities

It's all possible !!

Just to clarify a point eZee bikes are available with behind the seat post batteries that have capacities ranging from 11 up to 28AH, in addition there is the option of a second battery 14Ah fitted in a rear rack and wired in parallel which could give a total of 42Ah.

The aforementioned are all 36v, but the same eZee system will also run at 48v and there is 15Ah behind the seat post battery and an 11Ah rack mounted type.

All carrent eZee batteries have Sony V3 18650 cells.

Sorry john - I should have said you can also get higher capacity batteries in the same size - especially it seems in the behind the post design
