In which world is this "one of the cheapest e-bikes available"? 

Have you not done a simple search for example for 'e bike halfords' to find a large selection at £599?

That's fine guys, I quite like e-bikes too, just not in a motoring magazine. 

A big point for me is that this Decathlon isn't even the best e-bike you can buy for a 'grand'. Some have modern disc brakes, some are a bit lighter, some with lower frame mounted batteries, which helps the low speed handling, etc.

Look in a bike magazine or e-mobility websites, if you want to see some comparison tests.

For me this article is just about a bit of paid advertising in a motoring magazine and Autocar should highlight it as such.

Scrap, I agree, its good to include all forms of transport. Perhaps next week we can have a test between a trip on the bus compared to a train?

This review doesnt even tell you if this bike will take a fat chap up a hill without having to pedal! We surely need to know what the maximum weight for a 1 in 3 hill is. At least we could compare E Bikes on that basis!
