I now have a Cranbrook 55387 with a 4-stroke 49cc engine mounted. (I still haven’t done the initial test drive, btw.) The main failing of the bike in its current condition is the lack of a brake beyond the coaster rear-hub one. It needs a front brake. The options: 1. Get a new front fork (suspension?) with disk brake mounting holes. front wheel with a disk. disk brake. 2. Get a new disk brake adapter and put a brake on. 3. Get a rim-clamp (caliper) break, perhaps an extra-long-reach type. I measure 3.75 inches (9.5 cm) from the rim center to the hole where the fender was attached. The only one I could find with a reach that long was this from Niagra. Considering the reach is so long, and considering caliper brakes depend on a difficult-to-maintain true wheel, , a disk brake seems preferable. Do those adapters work? Where should I buy everything (wheel with disk, disk adapter or entire fork, brake itself)? What solutions do you advocate for the lack-of-front-brake situation? If you already were in this situation and bought a wheel or something, I'd appreciate directing me to the vendor you recommend. I'll just follow your footsteps. I hate buying from unknown companies, so a referral is helpful.
