It gets easier as you persist. I've now got some serious calf muscles and my thighs are more solid as well. Bum sore does not subside much though ....

You'll be catching and passing them guys pretty soon, with a smug smile on your face.
Racked up over 700 km on my bike now and cruise home at 35-45 kph quite often. Kind of makes the car drivers a bit annoyed for some obscure reason..
I'm off to a conference this weekend at Lake Taupo, be bringing back at least one new Ebike and most likely two. Also confirmed another conversion job for next week and a possible other one to follow. The two new bikes should be sold within a fortnight, I have enough interest already.
And then end of March, early April I'm running a seminar for about 30 people and a big Eco Day event with a stand and public display. Numbers to it last year was about 2000 attendee's.
Should score one or two out of that lot, they will be mostly greenies. Hopefully should have the second shipment of bikes in so have that available for demo and sale.
It's growing real fast over here as the Councils really are getting into it to curb traffic and congestion problems, especially in Auckland.
All good for me ..
