The yellow trike (1st photo) is a standard 26" bike BUT getting 20" wheels instead of the 26"
REASON I have a neighbor interested in purchasing said trike. She rode the blue "hammer head" last summer.
This lady has MS so IMO 20" wheels may be a better choice. Had to reconfigure the front brakes to accommodate the smaller wheels.
Waiting for new wheels and tires (no two exactly alike wheels in my collection). Ordered 48s x 20" wheels from
bargain basement bicycle parts https://bargainbasementbicycleparts.com/shop?olsPage=t/front-wheels
Plan to use only one gear (LOW). Have a two into one brake lever for front brakes.
Open for suggestions on improvements or additions
