pedals are both pulled and pushed. It is just a lot easier to climb a hill that way. I can also say that that my feet tends to last longer if I try not to press on the pedals all the time. By lifting the feet att the return stroke, I can avoid the aching feet I will otherwise have after some time pedalling. This, btw, seems to be a recumbent problem. For mechanical reasons I assume the force pressing the foot to the pedal is actually higher on a recumbent (with a near horizontal leg) than on an upright (I will do some calculations some day). My method to get a smooth round pedalling is to imagine my feet following the pedals, instead of pushing them. Try that, it gives a remarkable relaxed, flying feeling (on my Trice recumbent, at least)! The trouble is to keep this up for a prolonged time, some muscles seems to need training... Sverker

- My first impression of the Powercranks was a bit flawed. Their main principle is preventing "resting" (pushing if you like) on the pedal in the up-stroke. Learning to use muscles to lift the foot will increase effective power (theoretically). If the power contribution in the up-stroke remains small (but not negative) it will do nothing to smooth the power curve. This might work, but I'm sceptical. By the way: will this work at all on a recumbent? For me they are worthless anyway since I only ride Mountainbikes. - My own reasoning around the possible benefits of Bikedrive has made my so curious that I just might have to try it. I have my power reading Tacx to check with. Too bad about the extra 400g's. Maybe I can give first hand reports this spring ;). Loooong message.

Hej oss Dagen liggcykelträff regnade bort. Var visserligen på plats. Men bara jag, så jag körde hem, passerade en vallokal, passade på att ångerrösta. Allt medan regnet stundtals öste ner. Så låt oss satsa på någon snart kommande söndag. Skickar ut ett meddelande. Mvh Krister Spolander

S-Pedelec 45km/t i Sverige?
by Michael Kommant 03 Jun '18

03 Jun '18

Hej! Liten om mig: jag heter Michael, bor i Bremen (Tyskland) och driva en cykelaffär där. Jag cyklar varje dag med en HP Velotechnik Scorpion fs 20". I juli ska jag kommer till Sverige, den där gången med trehjuling och jag skulle vilja cyklar från Malmö till Västervik. Mestadels på Sverigeleden. Och nu en fråga: hur är det med snabb elcyklar i Sverige? S-Pedelec 45 km/t som vi kallar de här i Tyskland. De har en registreringsnummer och speciell försäkring. Finns de i Sverige också? Få jag cyklar med en HP Velotechnik Scorpion fs 26" S-Pedelec i Sverige? Ursäkta min fruktansvärt svenska... Tack så hemsk mycket! Hälsningar, Michael
