I had been doing some research on getting a motorized bike and the Golden Eagle Bike Engines motorized bicycles, running EHO25 25cc Robin/Subaru Mini 4 engines get about 225 miles per gallon. The similar EHO35 35cc Robin/Subaru Mini-4 gets about 200 MPG. I’ve seem this claim verified in a few places.
These are 1.1 and 1.6 horsepower 4 cycle engines made by Robin Subaru that weigh under 8 lbs… under 13 with mounting hardware. So that’s a 200 lb rider, 25 lb bike, 15 lb engine…
I’m thinking of getting a motorized bicycle because:
– You need a lot of motorcycle to go over the Bay Bridge comfortably…. 250CC, $3-5k used. A motorized bike costs $200 for the bike + $550 for the engine, new. I just saw a used bike and engine on Craigslist for $325.
– You need a lot of nerve to take a motorcycle over the Bay Bridge. Lane splitting is nerve wracking and dangerous. In the 1 month I’ve been here, I saw one bike almost get bowled over by a car that didn’t see the bike and moved into his lane (or he was being a super-duper asshole). And pretty much every lane splitting motorcycle I saw was inches away from disaster.
– I mostly want the motor so I can keep up with slow urban traffic… SF traffic peaks at about 35 mph
– It would be peachy keen if I could easily put a motorized bike on a bike rack hanging off the back of my car.
– It is convenient to combine a bike (that can be run under human power) with a vehicle with more range and speed. Electric bike batteries are too heavy and underpowered.
– A motorized bike compares favorably to a 150CC scooter:
- top speed: 30mph vs 50mph
- highway capable: no vs not really
- weight: 40lbs (can be carried up stairs) vs 200lbs
- mileage: 200mpg vs 65mpg
- safety factor in an accident: similar
- cost (new): $800 vs $2,500
- towability: bike rack vs trailer
- can be pedaled effectively: yes vs no
- passenger capacity: no vs yes
- hauling capacity: backpack & 1 panier vs backpack & 1-2 cubic foot storage space
- noise: similar volume (some scooters are very quiet, most scooters make a less annoying noise than a motorized bike)
- cool factor: novelty vs sleek
- insurance: free vs $400/year (approx)
A motorized bike wins in most of these categories. So why don’t I see more of them on the street??? Am I missing something?
- When riding in traffic lanes, especially at night, cars behind me might not see my (minimal compared to scooter) lights
- Cars won’t believe a bike can keep up so they’ll want to pass me, regardless of my speed
