I am looking at getting my average speed up because since June I have suddenly found myself doing more journeys over 50 km than anticipated. "Fast" for me is an average speed of up to 35 kph or more compared to my current 26 kph average.
This can be done within the limits of pedelec law on my standard route by using a bike with 28" wheels (700C) and correct gearing. At the moment with 26" wheels I can only pedal to 34-37 kph before spinning out at high cadence (90+) downhill.
I anticipate that pedaling uphill with maximum assist I will be able to maintain 27.5 kph (25 kph +10% legal tollerance) and downhill pedal to just over 50 kph (46x11 or 48x11 not decided yet) before spinning out at a cadence of 90. At my normal cadence of 60 I will be around 40ish a gain of 10 kph. I am pretty sure of the above numbers now that I have 1300 or so km under my belt and they are based on experience of the routes I take and my cycling habits.
The other solution is a moped (s-pedelec) which is legal here but bogged down with silly stupid helmet law. My favorite quote from the interweb "Why would an ebiker doing 25 mph need a different helmet than a lycra doing 25 mph? What's the mystical magic?"
So drivers licence/road code certificate, insurance, no more bicycle paths (only some are moped legal) and, in my case, riding with an illegal helmet. A helmet which is legal for Germany Switzerland, the Netherlands ad. nauseum but not for France or Spain... In France 90€ fine and three points off the drivers licence. Spain "up to 200€" fine and three points. There is an interesting clause in Spanish rode code "Every such certificate issued by the competent authority of a Member State of the European Community will be valid in Spain" which could mean that an s-pedelec helmet with a German certificate should be valid in Spain.
In an ideal world I will have two bikes: a pedelec for knocking about at distances up to 10 km from home and an s-pedelec for "fast" commutes on larger distances. Fortunately I have the parking space downstairs! The frame and fork for the s-pedelec are in front of me in my living room, just need to get it done ($£€
) and through individual inspection by the DRIRE before the first of January...
