Mountain bike for adrenaline, road bike for speed but old cruisers for the shear joy of riding a bike. Definitely not the way you want a ride to start out but after correcting self inflicted operating issues, all is well that ends well. I have to rethink my homemade shifter. 20 miles, steep grade, I have finally nailed the gearing, though my high end is lacking. Adding more gears equals cold spreading the drop outs, so I only have three gears to work with. Not exactly Redondo beach here.
Have you considered an e bike? 1960ish Rex Chrome frame with Frankenbike parts assortment, 5 speed SA hub and goes 35mph for 30 miles with throttle only. I built a couple of these as prototypes for a dude who must have run out of the Shark Tank $ lol and now they are mine .
