WHY RUNFAST IS THE HIGHEST QUALITY MOTORIZED BIKE ENGINE KIT IN THE WORLD
Heavier, stronger magnet rotor for more power! Other cheap bike engines use weaker, less powerful magnet rotors. Feel the difference!
Thicker, stronger, longer, stronger magneto cable wires for improved power transfer and better reach.
Heavier, thicker cylinder bodies and crank case for strength and durability!
Heavy duty metal engine for added strength and durability
Wider front mount for better bike fitting accommodations of all bikes
Front and rear mounting studs are rugged thick 8mm. Cheap low quality kits use thin, brittle studs that break off.
Enhanced universal motor mount clamp bracket for seamless bike tube front mounting.
High quality advanced u-bolt 8mm universal motor mount plate 8.8 grade 8mm bolts and nuts for ultra hold and grip
High grade 8.8 standard for all bolting hardware. The low quality cheap kits use 4.4 grade that strip threads easily.
Ungraded nylon insert lock nuts to prevent loosening. Low quality cheap bike engine kits use standard nuts that loosen over time
Balanced, heavy duty quality crank assembly with smooth rides.
Short crank rod for more power. Cheaper low quality bicycle engines use lightweight poorly balanced assemblies with the longer rod with less power
Longer camshaft arms for easier disengagement
Superior, longer clutch handle lever with correct (not inferior locking lever)
No button locking mechanism means that your button doesn’t pop
Off (common for cheap low quality kits)
Higher quality throttle grips that beat the low quality cheap brittle plastic connections that break after the first ride
Thicker kill switch cables not the low quality thin and cheap kill switch cables from
The cheap low quality kits
Superior woven throttle cable for super slick easy to twist throttle action. Cheaper, lower quality engine kits have cables that bind up in the cable housing promoting excess wear/damage on throttle grip.
Higher quality, thicker bevel gear grease for superior lubrications
Rugged, thicker high quality 8mm 4 bolt grade 8.8 chain tensioner for stronger, tighter frame grip. Cheaper, lower quality motorized bike kits use weak 6mm bolts and/or 2 bolt weak gripping connections and inferior 4.4 grade cheap stripping bolts
Superior chain tensioner pulley wheel with locking bolt. No need to jam a screwdriver in the back to tighten wheel. Superior pulley wheel with locking snap clip to prevent pulley from falling off of bearing! Cheap low quality kits don’t include this and have their pulleys fall off every time with disastrous consequences
Super thick heavy duty rear wheel sprockets! Low quality cheap motorized bike kits use thin, easy to warp sprockets that wobble and throw chains for disaster
Ultra heavy duty 415H chain standard for superior strength ride after ride. Low quality cheap motorized bike kits use 415 weak thin chains that break and snap.
High quality speed carburetors with correct tension throttle springs. Cheap low quality kits use stiff inappropriately tensioned springs causing excess throttle resistance and throttle grip damage.
Super wide 40mm intake for optimal air/gas flow. Cheap low quality kits use narrow 32mm intakes for inferior flow and weak running.
Superior hardened steel bucking bar for ultimate durability every time you need to disengage the clutch. Cheap low quality kits use cheap, low quality metal bucking bars that quickly wear down preventing proper clutch disengagement
Wider, more accommodating gas tank straps for easier mounting unlike the cheap low quality thin and stiff gas tank straps from
Higher quality fuel valve with superior stiff thick rubber gasket to allow for proper position of the gas valve unlike the cheap low quality motorized bike kits that provide thin red washer that prevents proper tank valve position crucial in opening and closing of the gas valve.
High quality fuel filter unlike the low quality cheap filters that the low quality cheap motorized bike kits provide
Longer, stronger high quality fuel line unlike the cheap low quality short gas line from cheap low quality motorized bike kits
Low quality cheap motorized bike kits
We at Runfast build and ride motorized bikes and demand the highest quality components direct from the manufacturer. Every detail counts. The cheap low quality bike engine kits don’t care and don’t understand the details that make a quality motorized bike engine kit.
With better qualities you save yourself from the headaches of cheap trash breaking down. That’s priceless.
