I have to agree with Alex on this one, my first purchase was going to be a Salisbury, at the last minute I went for a Powacycle folder, only because I already had a good MTB, and the folder would come in for public transport.
I now have 2 powacycles, another bought secondhand with little use from the previous owner.
I have taken the electric components off one bike and fitted them to a good MTB.
With just throttle I am hitting 18-19mph and on pedal assist 21mph. The gears are too low ratio at 14 teeth on the back cog.
An 11 tooth sprocket would make me go even faster
For legalities this was on a private road and of course restricted to the UK 15mph on public roads
Powacycle is not a refined bike and could be easily uprated, but at £399 I think that is where e-bikes should be coming in at.
Many of the e-bikes are over rated, even big names like GIANT (pardon the pun) are made in a factory where the same components are fitted to other makes but you are not paying for the name.
Marketing the bike or any brand through Makro isn't going to take the world by storm, IIRC it was Makro who stocked the Sinclair C5 at £399 and look what happened to it. (yes I know £399 in the 80's was a lot more in real terms)
If anything Tesco is probably the only way to make ebikes mainstream so that Joe Bloggs and his wife will have one.
I'm all for local business, recently I found out that the largest cycle warehouse in Europe is based not far from me (online only and only a couple of 'onion seller' style ebikes on their website)
But having said that, other local shops that I went into just didn't promote ebikes and were neither helpful as to where I could source parts or willing to buy in kits for me. In fact I found them arrogant and ignorant towards ebikes and potential ebike users.
