FSA CK-745, 15T ? At 9.90€ a pop you could try a couple up to 20T to see which suits you.

I have my blood washed twice weekly! In red wine :) I discovered spinning fast when I built my first e-bike, I used to be a strong lad pulling big ratios at slow cadence. Spinning just under two revs in less than a second isn't that fast when you analyse. I calculated my cadence by counting in...

I have an assistance level button! And I can change between assistance levels on the fly!!! Which means that most of the time I am in assistance level 2 of 5 and occasionally on steeper sections in level 5 of 5. The difference between riding on the road and riding off-road is probably the main...

http://www.triangles.pt/en/ "The company utilizes innovative technology in aluminum processing where the welding process is fully automated. Triangle’s is the first factory in the world to produce aluminum bike frames in an automated manner. Triangle’s was founded in 2015, with the...

Me at that time about 78 kg probably 79-80 kg today. The bike weighs about 25 kg at a guess. The GSM is a clone but Woosh would have to say where the power is. The controller is a KT 36v 15 Amp which I will upgrade to a 17 or 20 Amp @ 44.4v to have a faster cadence - 110 in theory. The motor...

Well they aren't building many frames with electricity generated by burning coal now for starters are they? They are certainly doing a better job at making industrial quantities of frames in the EU than the UK is... You see they are trying. Trying to compete is just as important as competing...

Yeah, best leave it to the Portuguese... :rolleyes:

Just checked the chain I bought and so far it has cost me 0.00€ per km rounding up to two numbers after the zero... :rolleyes: Or if you must less than 0.50€ per 100 km. :)

This is my favorite brand: https://www.bike-discount.de/en/wippermann-connex I have KMC on the trike and am not impressed where for a couple of € more the equivalent Wippermann is much quieter and smoother shifting on the pedelec.

OK thanks David. It seems you have chosen a responsable supplier (no surprise there given your general attitude on the forum :) ). The problem is what to do about the others. Attitudes towards the environment are changing pretty fast in China - let's hope it is fast enough, for the Chinese, they...

The problem is what the Chinese do with the stuff that doesn't make it into the bike tilson, not the material in itself. If they boxed it up and sent it off to construction sites to be used as reinforcing in the foundations of buildings or whatever no problem. Chucking the residues in the...

Great stuff! The GSM stalled on a 17-18% hill 900 metres long about 1/3 the way up. Gearing was 46:32 and 28" wheel. 32:32 it will climb 15% with me seated and in level 4 so about 250 W.

0%: A flat road 1-3%: Slightly uphill but not particularly challenging. A bit like riding into the wind. 4-6%: A manageable gradient that can cause fatigue over long periods. 7-9%: Starting to become uncomfortable for seasoned riders, and very challenging for new climbers. 10%-15%: A painful...

My longest ride with a 375 Wh 10.4 Ah bottle battery (Samsung 26F): Mxus XF08 with Shimano Mega-Range freewheel, 48 tooth chainwheel and 26" wheel with Michelin fat slicks (1.95" ?), steel frame, no suspension 59.3 km, 515 m climbing + ride to the station, 14 km and 164 m climb for a total...

Yes they think they are superior to the Scots, Welsh and Irish. Then they have a huge inferiority complex to Germany, France, Italy and Spain etc.: - great German sports cars weren't built in tiny little sheds - the French have better tasting food - the Italians dress well and are better...

The 46 was too big for me so I put a 42 on and it isn't enough... So I would say try a 44 before going smaller. I also have a 32 for climbing hills. I think my cassette is an 11-32 or maybe an 11-34. This is on a 28" wheel of course.

If there is power draw above the cutoff you have a problem :) You see on the KT LCD a very short draw of 3-5W or so from time to time when riding above the cutoff on my bike, I don't know where that power is going, topping up the capacitors in the controller?

They win the competition for the ugliest LCD screen on the market! I wonder if they are playing by the law and charging to 48v max?

That is the top speed of your motor, above that you are on your own.

Our neighbour had a bantam and I really yearned after it as a teen but he wouldn't sell it to me. He had replaced the broken muffler with a Milo tin with some home made baffles in because straight exhaust it scared the sheep silly...
