Here are my latest Bikes. A giant Elwood 21" frame with 700C wheels with a HT70cc. This is the most comfortable bike I've ever built. The larger wheels make such a difference to ride quality and the high bars and low saddle are so comfy to ride withj.
The Schwinn Alloy 7 had the HT 70cc for 2 weeks before I put the 4 stroke in.
The HT 70 was that rare thing - a good motor - just the luck of the draw. But the 4 stroke is lovely too except on hills.
