Re: what do you think about this electric bike?

If you are in good shape and are looking for no more than a gentle assist up hills it may be ok. Otherwise, 250 watts is too little power unless it can deliver more at peak load for brief periods. Even then they had better be *short* hills. With that rear hub motor setup I'd expect at least 350 watts, and preferably 500. The Prodeco I just bought (I think!) delivers 500, and claims to be able to produce 750 watts for short bursts. It's probably also heavier than this bike, but 250 is still too low.

But believe it or not, 250W is the legal maximum for electrical assitance of bicycles in many countries. In effect it almost doubles the power of two human legs :-)

My rides:
2017 Zero S ZF6.5 11kW, erider Thunder 5kW

True enough, but the extra weight from the drive pretty much subtracts one of those extra legs. ;-) I also suspect that many EuroBikes provide more than 250 watts for brief periods.

Actually it also comes in 500W/750W motor with option panasonic cell batteries, but just as "MEroller" said 250W is the legal maximum in many countries, and higher motors are usually more expensive than the normal one:)

Life is like riding a bicycle. To keep your balance you must keep moving.

I still stand by what I wrote, with the proviso that Europeans probably have stronger legs and smaller guts. ;-)

Re: what do you think about this electric bike?

Personally i prefer 500 W for my electric bike. As it gives enough torque and speed but also don't kill the battery. For europeans strong legs i also agree ;)

But i can also understand why they limit 250W as these are sold without licenses as a normal bicycle. So kids can ride it anywhere without restriction. So for that reason i can understand and approve the 250 W.

By the way this electric bike looks pretty cool. Where is the battery located ?

Re: what do you think about this electric bike?

I can see the battery pack on the front downtube. Electric bicycles are sold pretty much everywhere without a license. In the US they are generally either legal with few restrictions or not legal at all. With all the horrible ATVs kids ride here, a 500 watt bicycle is the least of parents' worries...

Re: what do you think about this electric bike?

I totally agree upon that. Yeah that ATV can be terrorising in some cases. After comments i checked the regulations in USA. Yeah there are restrictions but obvious that government don't care so much about it. I think still they won't care so much until couple of ppl seriously injured. As with bicycles it is easier to have more serious injuries.

Besides for such bicycle do you know where can i find ? i really want to buy an electric bicycle but don't like the ones where the battery can be seen. Also do you have any idea how much such electric bicycle can cost ?

Re: what do you think about this electric bike?

Where are you? Here in New York state electric bicycles are illegal for all but off-road uses, but in many locales they are ignored. 250-350 watt lithium-powered bikes in the US run about $800-$1000 USD. More powerful ones cost over a thousand. Lead-acid powered bikes are cheaper, but heavier and with generally shorter battery life. They are sold mainly online, but some large bicycle dealers and Walmart also sell some models.
