How much does the engine weigh?

Individual Engine Specs are different , depending on the engine - Total weight including all mounting parts range from 12 lbs to 14 lbs.

How loud are the engines?
All small engine are between 70db's at Idle to 85 db's at Full Throttle. 4-stroke engines are in the same range, it's the Tone many find less irritating that results in the "Quiet" reputation - the 2-stroke  is also, in this category.

Can I pedal with out the engine running?
YES...One of the features of our engines is that you can disengage the clutch with the  lever and the bike will pedal like normal.
You won't feel much drag, pedaling  for short distances, with tension lever Off. Pedaling longer distances And for engines with larger clutches, it's much easier.

What kind of fuel does it take?
The 2-stroke engines use Unleaded Gas, 87 octane or better with Quality 50:1 2-stroke mixing oil for Air Cooled engines - we Highly recommend synthetic Blends, not straight synthetic. or G.Oil 10X30 for Gren Engines .

For the 4-stroke engines, 87 octane, or better, is recommended and the oil you find runs best in your auto and/or recommended for weather conditions in your area.

Would a bicycle shop be a good place to take my engine for service?
No, many bicycle shops have a negative attitude, when it comes to motorizing a bike; they feel everyone should be in Lance's physical condition. If you don't have the time (or the inclination) to do the service yourself, take the unit to your neighborhood lawn and garden repair - these folks are familiar with engines And which end of the screwdriver to use!

When you say "pedal a few strokes" on take-off, what speed do you recommend before pulling on the throttle?
You don't have to pedal up to Any certain speed, just a few strokes to start the bike rolling, as you ease on the throttle. Taking off from a traffic light, I always pedal a few More strokes for a Faster take-off. When I say 'ease' on the throttle, I mean - Don't Yank it! Treat the machine with a little respect and you'll be rewarded for a Long time - these are Bicycle engines Not motorcycles (although some of these engines might argue that opinion).

Which engine is recommended as Commuter Transportation?
A general 'rule of thumb' would be to recommend a 2-stroke engine, most commuters are looking for the fastest speed - 2-strokes are faster and made to run full throttle all day (with 4-strokes, it's recommended to back off the throttle slightly for long range cruising).

What kind of Oil should I use?
For 2-stroke engines, use a quality oil expressly labeled: 50:1 Two Stroke mixing oil for Air cooled engines - and Only mix it 50 parts gas to 1 part oil. or G. Oil  10X30 for Green Engines. We highly recommend synthetic blends as opposed to straight synthetics.
4-stroke engines take automotive oil - and whatever is recommended for Your temperatures.

How do I change the Oil in my 4-stroke, Without having to turn the bike Upside down?
With a Basting Bulb - and Don't grab the one out of the kitchen - Unless you're Fast! A 3 - 4 inch piece of gas line (auto parts) stuck on the tip of the baster will facilitate the job.

What features should I look for in a bike - Specifically to motorize?
Specifically? 36 spoke (Stainless steel spokes) wheels, solid axle (not a quick release) and Rim brakes will simplify the process - Then #1, find a bike that's Comfortable for You! Fenders, rear view mirror, speedometer and a Nice Fat Comfort Saddle, our customers find they spend a Lot more time on their motors  than they Ever did on a pedal bike.

Any problems reported with Disk brakes?
Disk brakes put a lot of stress on spokes, addition of engine doubles the stress, maintenance might get expensive.

Some disk brakes only require the lower mount strap be spaced out with a nut/washer for proper mounting - Others find they have to grind a 1/4" wedge from the lower strap to clear the brake, still others require Serious modification of the mount and would not be recommended.

Do I need a driver's license to ride one of these?
No, in most states our engines does not classify as a motor vehicle/moped. Check your local laws to be safe.

Can I add an additional muffler to reduce noise?
No, unless it's approved specifically for that engine, we do not recommend additional mufflers or silencers. Restricting exhaust flow can cause engine to overheat, reducing life and/or loss of performance. Warranty does not cover use of any unauthorized parts. An exhaust Tip that turns noise away from rider's ear, back and toward the street - makes a difference without causing air restriction, overheating or loss of performance.

Do you recommend a particular kind of Bicycle to use with engines?
Anny bicycles that have “V” frame with space of 16” to 18” of
opening is good - Hard tale only - no full suspension, front suspension ok

What are the differences between a 2 stroke and a 4 stroke engine?
Explanation between these two different types of engines.
The choice between 2 or 4 stroke engine is dictated by personal choice, riding style, weight load and terrain. If your primary purpose is commuting, or require a faster top speed - you may be more interested in a 2-stroke. If you pull a trailer and/or anticipate cruising at slower speeds, you may be better suited with a 4-stroke engine.


2-Stroke engines: smoother running; faster speeds, lighter weight, runs cleaner at faster speeds.
Continuous cruising at slow speeds will cause more rapid carbon build-up, and require more frequent maintenance.
Requires gasoline, pre-mixed w/2-stroke oil before filling tanks but very little maintenance.
Clean spark arrestor and exhaust ports after a few thousand miles (the 1st time) -becomes less frequent after engine breaks in..
Only 3 moving parts.
87 octane, or better, non-ethanol.
*** Never mix fuel rich even on break-in! Always mix 50 to 1 (One US gallon gasoline to 2.6 oz Two- stroke mixing oil). For Air cooled engines; synthetic blend or 10X30 G. Oil for Green Engines - not straight synthetic oil.

4-Stroke engines: a lot of low end torque at slower speeds, engine runs clean cruising at slow speeds
Not recommended to run at absolute full throttle for extended periods of time, but to back off slightly, for continuous running.
Convenience of pulling into closest service station when low on fuel but must add oil occasionally and periodic oil changes.
11 moving parts - eventually requires valve adjustment (many thousands of miles but depends on your riding style).
87 octane, or better, non-ethanol gasoline and automotive oil.
*** 4-stroke engines Add oil before running engine (less than 3 oz) but don't Overfill - keep oil level below Full indicator on dipstick. When checking oil level, Push dipstick in - Don't screw it in - just push in, like checking oil level on auto dipstick. Check oil level when engine is cool, before starting or allow engine to cool a minimum of 5-10 minutes after running, before checking oil level.

Too much oil will cause oil to be sucked into the PVC valve, won't hurt the engine but will make a smelly mess till it's cleaned/run out. Hard trail riders may want to drop oil level even lower, i.e.. half way between Full and Low indicators on dipstick.
