Will Bosch ever be taken to court like Epson was for preventing its printers from working with third party cartridges? It is a blatantly obvious case of locking people in then milking them when they have to replace a battery. Another good reason for building your own bike. Do it while you can...

Those are 8.25 Amp discharge cells so if you have a 48v motor with a 20 A controller you are over stressing them, I am not surprised you get that range.

Well then that is false advertising and there are laws against that! GA cells have a nominative 3350 mAh capacity from the manufacturer. You may get some more in real life then again you may get a little less...

How do you get 17.5 Ah from a GA? 5P = 16.75 and 6P = 20.1... 5 x 10 A = 50 A discharge 6 x 10 A = 60 A discharge The 30Q batteries are more honest in their description and 4P also delivers 60 A discharge. That is why I put them in first place.

1. 30Q cells 2. GA cells Stay away from 29E at less than 6P13S

In 50 years I'll certainly be flying around up there somewhere... :D

An attic bike (8 years unloved by previous owner), rear hub motor kit, I added tyres, mudguards, front brake, grips, seat and lock, everything else is stock. 3600km on this one in 12 months: A skip bike found by a mate on his way back from a caté at 2 a.m., mid-motor kit from Woosh, it has...

Boris wants a road tunnel. Will work with electric cars as long as there are no lithium battery fires! Too long to evacuate petrol fumes without a chimney or two and they risk being run into by ships... So no lorries, that is why the current tunnel works the way it does.

OK understood.

The light was on the wrong side? Bikes lights only point straight ahead. Don't they?

Seriously when you pick an orange each day between when it is picked and when it is eaten/juiced a percentage of vitamin C is lost. SA will have to pick green so that the fruit survives the trip in container, why do you think the best Florida orange juice with the most vitamin C is the stuff...

And shipping from SA is much faster and cheaper than bringing them over on a lorry from Spain...

Your theoretical top speed will be 42.36 km/h http://www.bikecalc.com/speed_at_cadence At over 25 km/h you are going to need to fight air resistance and that is where the motor comes in... I am a reasonably fit 60+ yr old man weighing about 80 kg on a bike weighing 23+ kg. I have ergotec flat...

You should be able to get 45 km/h (28 mph) from a 36v BBS01, I can from the GSM. The secret is using the right gears and spinning at 80 rpm - 700C x 38 tyre at 80 rpm gives 44 km/h using 46:11 ratio. I have 700C 2" Big Ben tyres 42:11 and spin at about 90 rpm...

I did my little flat road, keep legs in shape 28 km ride thanks to brilliant sunshine today. On the way back I passed a pedelec! I hope I left him enough room when passing... :D Older guy on a Giant step through. He came back a couple of times on the uphill bits but not within 300 metres and on...

Here the older you look the less they stop. Secret weapon? Walk a dog, they stop for dogs not for people...

That will never happen unless you turn off all the cell phone towers... :D

1. choose correct length 2. never over-stretch 3. use the attach points which are on all modern racks 4. no more rat trap!

No it is a moped.

Which would mean that I, as a father, couldn't hug one of my sons in public? Such a law in Spain would have 99.9% of the population in jail! That is one of the disturbing aspects about your "Englishness" the lack of physical contact and your need for a magic protective wall - no brushing with...
