My thoughts are that they're nice, but curious to know the price. The C5 was technically the first 'velocycle', and a recent Google shows lots of companies making similar powered bicycle attempts like the one you've shown. Only three out of a list of about 30 companies brought up a price. One, made in Germany, was over €4,000. One, British, similar to yours was about £2,500. The cheap exception was the Sinclair X1 at £599. So yep, pretty, but show me a price before I open my chequebook ;-)
