Makes me want to have one... but it looks so expensive!

Tried to have a run a 36v. It works flawlessly. It runs at 20mph and uses 450W constant. This motor is less efficient than my Mac motor. At the same speed I think the mac would use around 350W-400W constant

Ok, I've set the voltage to 43V to see if the controller can handle 36V battery... it can! It has a no load power consumption of 25W at 26V And a no load power consumption of 50W at 43V The wheel is untrue, I have to fix it and see tomorrow how the motor is working on 36V set up. If good...

Finally found it. The brake sensor was turned on!! Unplugged it and it works now! Let's see how it goes :)

Pedal sensor seems to be correctly fitted: And all wiring is connected: I'm scratching my head and wondering if the controller is down...

I've started to put the controller on 24V and move the pedal to see if the motor is working: Nothing was happening... like no power at all. The power light is turned on:

Hello John, I'm good. Back to France now and still having both my bromptons :) Nowaday I'm thinking to also have a bigger bike for more comfort, pavements and stairs are really annoying. I took this bike mainly for the motor, I can definitely send it to you for free ;) However because of the...

I went to paris cycle show last week and I've seen many bikes with Direct drive motor. I can't see the value of direct drive over geared on low powered bikes. They have drag and are less efficient during acceleration. But I've seen many constructor with these DD motors. I understand they have...

yeah he took off everything possible to get the bike lighter. I was thinking such a bike with a goldant motor would be under 10kg with battery. That would be quite crazy an e-brompton under 10kg

Thanks Dave, I know I can buy a new battery but it's quite expensive for such a cheap bike. This bike when new cost 150GBP. (with gel battery), but at 20.86kg it's a really heavy bike. And I was wondering if I shall go into the trouble to fix it?

Hello all, Someone sold me his ebike for spare for 50GBP: Apparently the bike isn't in production anymore. I was initially thinking to use the bike as spare and just take the motor out of it. But finally the bike doesn't seem so bad, although I weighed it at 20.86kg without...

Wowowow, I've seen it on ebay: Brompton Lacquer Titanium Bike X 6 87kg W Birdy BD 1 Rims Collectors Moulton | eBay That is SOOO lightweight. If only I had money I'd buy it. That's a bike for Jerry ;)

I might be interested depending on the negociated and shipping price

No problem, I just wanted to tell you. I always upgrade my equipment and re-sell other. I'm ordered a bunch of these Konion V3 cells. Will tell you my result when I'll receive them

Jerry, I've just discovered the new Konion US18650V3 cells: http://www.repasebaterii.cz/files/img/datasheet/us18650v3.pdf They are "only" at 185wh/kg (that's still 2 times ligther than your current Konion) and don't need BMS. This guys is located in Luxembourg and can weld them for you...

I think it happens when you puncture the cell

Additional safety information from NASA test on the NCR18650 cells: https://batteryworkshop.msfc.nasa.gov/presentations/Perf_Safe_Test_Panasonic_Li-Ion_NCR_18650_Cells_JRead.pdf I think I'm going to order the NCR18650PF and see how it goes

At 2p configuration with BMS you'd have a 36v5.5AH for 1.1kg. So slightly heavy than your lightest 3AH konion cell at 1kg without BMS?

Yes you have to use BMS, but they are 2 times lighter so even adding a BMS would give you a lighter pack. Let's say for example you get the NCR18650PF (new model of the PD with better soldering end): 18650 2900mah 10A discharge Panasonic NCR18650PF 3.6V high power battery cell 47g/cell at...

Actually I've just seen this: http://www.embedded-world.eu/fileadmin/user_upload/pdf/batterie2011/Sonnemann_Panasonic.pdf Apparently the highest energy density are the NCR18650A cells...
