Alomejor Bicycle Engine 49CC 4 Stroke Gas Engine Motor for DIY Bicycle Bike Conversion Motorized Bike Kit

Product Information

Sorry hellboy i wasn't trying to poke fun at you sometimes i just can't help to be a smart A** I wasn't trying to insult you at all, i know how impatient you can be waiting for a new bike I'm on my 3rd bike and everytime i get a new one i try to find out as much info in advance as i can don't take it to heart i was just messin with ya a little, it will be very obvious when you get the bike like i said it's on the left side down low on the block and mine actually had a long white sticker on the top of the motor on the transmission case that had a real long number on it but the serial number was the very first part of the number on the sticker so check both places and let us know what it says also look at the number cast on the head. or 55 tooth wheel sprockets may work as far as gear ratios go if the bike will be used on flat ground only, it is a little risky using that high of a gear ratio though because it could overheat the motor. the problem is that a lot of the engines stamped 48 and 49cc are actually 72cc, when you remove the head you can measure the bore size and you will notice that almost every engine stamped 48cc that I have come across is actually 72cc.

I can make the kit without the sprockets and chain and you could decide on that when you pick the kit up if you want.of the sellers have no idea what they are talking about and put too much jibberish out there that people listen to. the cc size of the engine is a function of the bore (diameter of the piston) and stroke (length of travel of the piston) together as you can see above some models have the same piston dia. To answer the earlier question that it takes more than bore size to determine the size of the engine, the answer is of course it does unless we already know what each size engine uses and the bore will tell you which model you have without having to measure the stroke. All of the power that is needed to move a vehicle goes towards overcoming drag (air resistance) on flat ground, and drag plus gravity on grades. I usually answer questions and help people in this forum in the evening, so if you let me know that you purchased the kit online through this forum I may not see the message in time.

Also, I am unsure how to connect the fuse to the battery pack and in general, wiring the fuse, key switch, battery pack, and controller together. It is not very difficult at all and you really need very very few modifications just a great product. Is it needed to have a freewheel attached to the sprocket, as on many bikes, or can the sprocket be attached straight to the back wheel? Similar to an engine for a scooter or goped, you simply pull the starter chord and hit the throttle to go!

True, Just like honda the china motors use the same crank for the 49, and the 70 which will be the same stroke. Startup is a breeze and you can stop the engine with a simple killswitch provided with the throttle assembly. Someone told me that 49 cc works better, he actually put my old 49cc on his bike and said it works great! They are generally faster and have a faster piston engine, while 49cc engines are generally more efficient and have a more powerful components.

Come join the discussion about performance, modifications, wiring, classifieds, troubleshooting, maintenance, reviews, and more!Or I can include the sprockets and chain with the kit if you let me know which wheel sprocket you want to use? If an 800 Watt motor is properly geared it will increase the ride time by over 20% compared to a 1000 Watt motor with the trade off being that the bike will have a 20% slower top speed. is not responsible for include among other things: falling, collisions with pedestrians, street, highway or roadway vehicles, striking obstructions or other person, unsafe weather conditions including temperature exposure, hypothermia, sunstroke, sunburn, heat exhaustion and dehydration. While the 4-stroke engine is generally lighter and have a stronger hole compared to 4-stroke engines. However, 49cc engines are generally more powerful, 49cc engines are generally more powerful than 49cc engines.

With these strict quality assurance measures, we are able to offer an industry leading 6 month warranty! The amount that the freewheel will increase ride time is proportionate to the percent of time that bike is freewheeling when it is being used.Don't be fooled by other retailers, selling outdated, non-EPA approved, old generation bicycle engine kits! it's a bigger fist punching, but there's a lot to be said abt a lighter piston and how high it can rev all else being equal. My goal is to try to be in the 25-30 mph range (I'm very light), and I'm not sure which voltage of motor to use, and what amp hour battery would be sufficient.
