No problem. :) Where I used to live at one time, all the municipal buses were trolleybuses, quiet, very powerful and connected to the mains all the time. The chumps got rid of them in 1969, in favour of diesel buses. I bet they are kicking themselves now! .

Yes, my Nissan Leaf e-car has a 400 volt 100Ah battery under my seat. But that is very different from pedelecs in numerous ways. Pedelec batteries are more exposed to damage, removable for charging indoors, easily tampered with and don't have the accepted connector standards and very...

It depends what that means. It could mean only when running connected to the mains, as some TV sets and laptops are, battery voltage supplied but run while connected to the mains. Others in here have been adamant that 72 volts is not acceptable. Anyway, who would want to cycle a 72 volt...

But of course a 72 volt lithium battery fully charged will be at almost 82 volts, way over the 75 volt DC limit. .

I dont remember the exact figure in the regulations, but it's a design regulation. Its over 50 volts, but 72 volts isn't permitted on these light applications. It's an EU regulation but we retain all of those via the Great Repeal Bill which wrote them into UK law. 48 volts or it's peak...

Reminds me of the Ezee Quando and Torq, both using the identical electrical setup. With no controller limiting, the 20" wheel Quando's assist speed ranged from 16mph down to 14 mph as the battery discharged. The Torq with the motor in a 27" wheel (700c) would spin to 26 mph with the motor...

Theoretically you can achieve the big speed increase you want by changing to a 72 volt battery. BUT and it's big but, that voltage is illegal, you'd have to buy a controller that could handle 72 volts and replace your battery with a 72 volt one. So costing a huge amount, the bigger battery...

Seconding Neal's comments, it's rare for a hub motor to have a wind that can exceed 16 mph in a 20" wheel. I only recall one offhand, an A2B 20" wheel model that had a wind for 20 mph. With your's already on 48 volts it's unlikely you'll achieve more with that motor. As a general rule with...

Long ago I established a method that many members have followed. It separate the value of th battery from that of th bike, since the battery life is shorter than that of the bike. Here's the updated version: Two year old e-bike: Half the current replacement cost of a battery is established to...

It isn't in any way a system. It's merely a change in British law to allow drivers to legally view etc in the stated conditions in any vehicle with autonomous capabilities. The decision whether to use it is left to the driver, another impossibility for the police to try to sort out. .

The designers on the continent where large numbers of pedelecs are made, including where you live in Germany, don't agree. Nor do the Japanese, another major manufacturing centre for them. For them the pedelec sensor is the cutout. Given that the Germans buy half a million pedelecs a year and...

It's a sales promotion for Bosch equipped pedelecs. A notional assurance to potential pedelecers that choosing a Bosch equipped bike instead of any other might offer en route charging, should that ever be needed. .

You aren't imposing in any way Tom, we are always happy to help. It's yes to having a larger capacity battery and the increased range it will give. I'm afraid I dont have an answer on the warranty they give. .

Apologies for the delay, you're in now, riding on the embankment by the river: Map Link .

Large lithium batteries can't be flown on normal courier services is probably the reason. Fire risk. .

They'll both be ok here under this new law. .

My Nissan ProPilot is just as bad. If a pedestrian walks off the kerb into its path, it brakes. Great, just what it should do. Snag is that when I turn into a local road which commences with a bridge arch, because the front of the car is heading towards the arch pillar as the car swings...

Most suppliers seem to be out of stock of the 36 volt Silverfish, but this link with good ebay feedback has some at a good price. Doesn't seem to include a new base though. .

They used a 36 volt 10 Ah battery that looks like the Silver Fish one. I'm not familiar with those and their base connections but others are and I'm sure will advise. The photo below shows an Eagle with that battery in place. Later they were fitted with larger range batteries which will do...

Plus re-establish the milk marketing board and get rid of prescription charges, together with what they've already stolen from Labour, you'd have a traditional Labour manifesto from long, long ago. Add 83% capital gains tax and 66% purchase tax on luxury goods (everything that ordinary people...
