I've long been involved with bikes, whole family has and did quite a bit of touring, crossed the US twice, and a did a fair amount of local road touring and mountain biking as well. Having passed the six ohs in age, the hills have gotten steeper than I remember them being, lol. I've found a solution that works for me. Here's one of my bikes.<br><br>Proflex was the brainchild of Bob Girvin, made in Woonsocket RI and the first <em>production</em> full suspension mountain bikes made. Always wanted one and mine started as a rehab project, came in pieces in a box. I rebuilt it from the bottom bracket up including front forks and swing arm pivot. It's been retired from serious trail beating. I detuned the suspension for use on the road and put street slicks on it, makes for a nice cushy ride.<br><br>To level out the hills some, I added an assist, 33cc 4 stroke made by Subaru industrial duty motor, smooth, quiet and highly reliable. I don't use the assist all the time just when I need it. The system freewheels when not in use, adds approx just 14 lbs with fuel and averages somewhere around 175+ mpg. Frankly, at my age, my time on the bike would diminish greatly without it. <br><br>This type of set-up I know will always be a part of any travel adventures in my future. The bike w/assist weighs in at 44 lbs, can easy be lifted and carried on a sturdy bike rack, offers both exercise and utility to cover extensive ground and be IMO a great complement to a nomad type lifestyle. This ends up IMO being far better than a moped or scooter, much lighter and able to effectively pedal it if and when you need to. Also, the small ICE (int comb eng) is a better solution IMO than existing electric options as I've built a number of eBikes (but that's another discussion).
