There is even one with the frame in the battery! Crazy Chinese when will they stop innovating... :rolleyes: http://www.ebay.co.uk/itm/Electric-Bike-250W-36V-Frame-in-Battery-Electric-Bicycle-26-Mountain-ebike

The GSM (a Bafang clone) easily does 40-45 km/h on the flat unrestricted. It is best to get a bigger/better battery than you think you can afford. It is going to be around for a while (3 years at least) so you will get ROI.

I also looked at the KMX (Tornado), what put me off was the direct steering and the disk brakes and the bucket seat... Too many components to upgrade to make it work for me. So I have doubled my project budget and get in return SA 90 mm brakes (they don't fade on steep descents), a mesh seat...

The motor and LCD will handle 48 V but the internal controller won't...

Now you know why I have a GSM with external controller :) Yes you can mix but you will only get +90% of 6000mAh out of the battery i.e. the lowest capacity Ah value. I forgot to say they you can expect >90% of the nominative Ah from Graphene compared to about 85% from Multistar if you use them...

The Russian who made the image says that even at 25 km/h and below air resistance is significative, it is our perception that makes us only start to feel it at 30 km/h and above. Then if you add the head wind factor it is even more significant below 25 km/h, you only need a 20 km/h head "breeze"...

D8ve is no longer here so someone has to take up the "bent" banner :) I found this interesting image: The average bent rider is offering about as much frontal area as a competition rider tucked up into aero position on a road bike. This will affect both top speed and battery range, D8ve was...

https://www.theguardian.com/commentisfree/2017/jul/16/manchesters-bike-share-scheme-isnt-working-because-people-dont-know-how-to-share I can't air my views on this in clear because tilson will say I'm being an a-hole. But I bet you can guess what I am thinking. These are the people that go on...

You have a typo d8veh, 36 V 6 Ah. :) Show us a photo of the bottom please. I guess that is where the wire comes out. Two of those in parallel is still only 2.17 kg ! Would work great with a BBS01 or GSM with internal controller!

This guy over on ES ran a Quest model through his aerodynamics software I think? He did the Elf and his own two designs too. https://endless-sphere.com/forums/viewtopic.php?f=28&t=62827&sid=99cc54764ea3deb3e1a5e60eaa5e6415&start=275

I was just thinking that if the UK wanted to sail off and stir up some trouble somewhere to the east (Remember Iraq?...) and the French said "Sorry, we aren't going" it could become very embarrassing.

Yes they are good. I love them! They charge faster than Multistar without any visible puffing (already very slight on Multistar), stay balanced provide plenty of power without sag... I am running Multistar and Graphene 10000 mAh 6S and 4S packs paralleled and in series for 20 Ah 37 V...

My experience with 32:34 is coherent with http://www.bikecalc.com/speed_at_cadence and gives between 9 and 10 km/h at cadence, seated, on a hill with +10% gradients the motor drawing less than 200 W most of the way! Air resistance: 2.9 W/km for the Quest(!) @ 40 km/h I am guessing that more...

Pasta salad!

Oh! The naughty men! Wrecking Britain just when you were doing such a good job all by yourselves! Bloody French, never trusted them! All that smelly garlic and cheese, they don't even make decent beer! In the EU there are rules on financial incentives, anything beyond would be corruption. So...

But... But France is in the EU! Oh deary me o_O more complications ahead.

Yesterday for the first time I paralleled 10 Ah LiPo with my very tired bottle battery. I was checking voltages on the batteries and as they were within 0.02v I decided to give it a try. Worked a treat, 0.5 V sag on the steepish hill on the way to the port and power to spare. Very heavy package...

Idea: how about trying austerity for the rich? It isn't working for the poor...

The SA is pretty good. Say you have a 53-38 mounted on your Bafang, GSM whatever with a 26"wheel at cadence (80-90) that gives speed range between 8.5 km/h and 66.5 km/h with an 11-34 cassette (max recommended by SA).

No. As for your question on the batteries in the container - charge them to 38.5 V (or within a few tenths of V) and they will be in storage mode and should show exactly the same voltage when they arrive.
