You haven't seen many German trekking bikes then? A lot of them have Magura HS11 hydraulic rim brakes. They weigh much less than disks They brake just as well (think disk that is 28" in diameter...) It is up to the kit maker to choose to sell one rim fits all or specific rims for disks and...

Going flat out (a power output of 250 watts) = 50 km/h (31 mph). So this is a car capable of over twice the speed limit too, the pedelec speed limit that is :D

They will have to sell it as "demonstration model" with a discount. How much does a bike devalue after it leaves the door for a test ride?

Turnigy Neutron 80W charger because it seems to do everything I need (and LiHV if and when) for 30€. If I get serious about Lipo I will get a more serious charger. I bought a bag of XT60 plugs and XT60 series connecter so will start off by replacing the XT90s and put the XT60s behind both...

Oh right! I feel much better but am still on the right side of 12 Wh/mile :D I bet if I didn't use assistance level 4 and 5 I could get down to 5.5 Wh/km. In fact tomorrow I start the experiment with controller limited to 11 Amps peak :cool:

Not the ones we have on the forum! :rolleyes: I don't have a car... :p

What is it with the Greeks? Did you mean grease (yeah like the ghastly film) inside (like in it)? Your favorite spelling nazi strikes again :D:rolleyes:o_O

I am still trying to get over the once and that was years ago... :(

My second order with all the missing bits just shipped this evening so next week will be my Lipoly initiation. XT60plugs and wire and charger and Watt meter etc. etc. SWMBO is providing the power supply from the computer she bought to help her daughter to pass her Baccalauréat I am guessing...

I had my Eureka moment (this has been trotting in my mind since last week). Going up hills I use 10-14 Wh/km and going down 0 Wh/km! As in my neck of the woods you are either going up or coming back down the average is around 5-7 Wh/km. So yes! I do need electrical assistance but only on half...

Today's offer 4S 20 Ah at 46 € three of those in series gets you a 48 V 12S 20 Ah pack for under 140 €... And you will be sipping from it at 1C or less (thinking of the GSM with the controller set to max 18 Amps).

So it is not just me seeing a difference when changing to 12 magnet PAS! Great to hear.

Nice design! My only quibble is the seat post, a NCX would be better and not affect the price too much.

I agree, that temperature is well outside the recommended use and storage temperatures for Li-Ion. For use you will need a battery cover. Range will be up to -30%.

:) I love inventive people! Hey guys we have another inventor! :)

My post is about the legality of having a dongle on the bike. If it isn't helping you break the law it can't be an illegal device. The motor power will never be higher than the manufacturers designed limit but a dongle could give you access to the full power of the Bosch motor (350 W...

If you have a dongled pedelec and the assistance is set so that it cuts out at 25 km/h it is still a pedelec. The nominative power is the same you have in no way modified that. The point of law is using a device to get around the cut out speed, that is illegal. If it (the dongle) is mounted and...

Because they are on promotion. Grrrr almost the same price I paid for the 4S 10 Ah... Which are no longer on promotion Yay! I got it at the right price. I measured and 16 Ah won't fit so it looks like a 4 pack 20 Ah set up is my way forward still waiting on charger so I can test what I have...

We are talking about EN15194? That is the only law here in France for pedelecs. "3.22 continuous rated power continuous (or constant) output power specified by manufacturer, at which the motor reaches its thermal equilibrium at given ambient conditions NOTE Thermal equilibrium: temperatures of...

No the GSM motor is legal, going over 25 km/h with assistance isn't. A 500W capable motor that is labled "250W nominative" is legally a 250W motor because the manufacturer says so. I hope these points help you with the understanding of the law.
