A recumbent would be best but that is probably outside most people's comfort zone. So if it's a diamond frame bike go for a good road machine with 700c wheels. Disk brakes are best. And hub gears also help reduce maintance and ease use. Expect over an hour each way until you get the legs and...

I haven't riden one but has it not got an 8 speed hub drive? This should give you a higher top speed but like most compacts you don't expect to cruse at 20 mph especially with electric motor. 15 is usually easy 18 is a real struggle. ( on the flat of course) And welcome

It's cheap and outperforms any other bike made. It breaks the laws of physics as we understand. It's a great way to get a lot of money from investors. I wish I had thought of it. Please send cheques to my Nigerian bank account. Just my quick assessment.

The old test for motor power was could it produce X watts continually? It was to confirm a minimum power output. This gives a continus power rating not maximum as it was assumed the motor would be rated at max level. Ie my car can do 150 mph etc. The manufacturers realised that they could rate...

The usable fuel cell designs use methanol as a fuel not straight hydrogen. Transporting and storing H2 is difficult and dangerous. But not illegal as far as I'm aware.

Andy you gave the dealer the whole bike. They only took the wheel the default is not your responsibility. New bike time. And sale of goods act merchantable quality. Dose it do what you expect? A dead rear light needs replacing and isn't enough on its own to return the bike but no electric drive...

Use this calculator for speed. http://www.hembrow.eu/personal/kreuzotter/espeed.htm 2kw gives 60 to 90 kph depending on bike and position. But road surface has a considerable effect at these speed and power levels.

Welcome Joe Why no crank drive systems. They can be quite power efficient?

Nice looking build the best use of a Sakura I have ever seen.

My first thought worst case is SLA at max charge circa 15 volts gives 60 volts at terminal. With 12 s lipo that's 5 volts a cell if you parallel them up. That could be press button and run time. A virtual bomb.

If it's a 50watt charger then about 2 amps max for 6s anyhow. How many watts is the charger rated at?

Si you will have to do a reveiw at one week,month and year. The bikes look quite distinctive and the price you paid was excellent.

It's a new vehicle type with no history to judge claim risk on so they are classing it as very risky?

I got my wife a vacum cleaner for her birthday,,,,,, :-(

But you said trips to the shops See quote from you earlier on your 500 to 10kw build! Its just 24s 5ah for quick runs to the shop and round the forest next to me. I have 2 triangle bags, one for each side which can take another 10ah but yet to try it out. If I don't want the bike to be crazzy...

When I were a lad 15 mph training speed 17 to 20 in a small bunch 22 good going for a time trial 25 realy fast for a hour. All these on a road bike with 10 speed gears. So doing 18 mph is fast for a cycle on the flat unless your a lycra God. Or riding a recumbent of course

No BH race not Neo, or Kalhoff pro? And defiantly not a hybrid of BH kalhoff that I have

Yup that's a nice looking bike at a price that should scare the competion.

Yes a bigger charger and power supply better to go for over 200watts if possible even if it costs a little extra. The charger can have circuits to up the voltage and inefficiency,s here all add up to the excess heat generation. I normally would suggest D8veh is more expert than me and listen to...
