E-Bike - What to buy?

[humanbeing]

Friend of mine is looking for an ebike to take back to Europe.
Any recommendation on a reliable, not to heavy, compact model?

And even more, anybody know a cluster of shops in Beijing to check the market?

Thanks
André

Japanese e-bike is best in quality . The used is selling from Y1000 up
