Battle of the Beasts: Unmasking the Superior Bike Engine | BikeBerry Showdown

I bought a 4-stroke kit from BikeBerry, very nice kit, I also purchased the 56 tooth BBR hub Sprocket kit. Worked great lots of pulling power top speed about 22 mph. I am a bigger rider pulled me great. Hills were no problem.

thanks for the review!

Definitely put a speedometer on!

I have the bt80 I bought just as the pandemic got bad here July 2020 still have it just recently put it on a 26" bike with 24" wheels and front fork for brakes. I'm running a 36t sprocket windowed piston with g2 reed and an nt carb. I cannot pedal this bike until I switch to wide arm crank I don't weigh a bunch probably around 130 but I can take off easily and very quickly without assisting the motor at all you gotta play with that baffle pull it out and put a nut on the inside to where it leaves a couple millimeters between baffle and exhaust so you can see straight through from the side. Your just using the nut on the inside as a stopper and something to solidify the baffle. The more you pull it out the better low end torque with a couple mph shaved off the top at least in my experience over the last 3 years. This was actually my first build ever it's probably been on 6 or more different frames just because I kept changing my mind on the style I wanted it to be. I would like to see you with a speedometer I hit 41 on mine just the other day with the setup I mentioned above I wanna see what yours does stock.

Is there anyway you can show the modification done to that frame. I really like the bicycle frame and would love to use the same engine on it

Can a torque converter be installed on the 49cc? I bought one of those from BB like 5 years ago and those transmissions weren't good...the clutch bell had to be welded a few times before it couldn't be anymore

I really would like to see what would you pull on my racers.

Do y'all have more vids then just one or where can I look it up to be sure 1 vid does no justice 💯💯 SPENDING MONEY

Is there a slim kit for the pull start side?

The Bike Berry transmission while somewhat slower than standard gives you such a smooth takeoff. I think it really saves the wear on the clutch. My experience with the 2 strokes is much more limited.

Are the new wheels on website for sale

Thanks! I'm sick of the crappy Huasheng! I'm copping a Bullet train. No one else has done a comparison.

I'm surprised that you don't use the carbs with the handlebar mounted choke lever

i dont really think it was a fair test . your comparing a 49cc four stroke to a 80 cc 2 stroke . bikes look great by the way love the tank on the board track racer look a like . (bt) . would love to have that tank on my bike . but like i was saying if you could find a equal sized engine to pair the bikes against you would see the four stroke would eat it alive . in power speed and dependability. just my opinion brother . i mean the 4 stroke pretty much beat the bullet train in everything but speed and the bullet train is almost twice the size as the four stroke . but dont get me wrong i like the bullet train as well . its a really nice engine .

4 stroke all day. Less maintenance. Less noise. Less intrusive to the ride. Better awareness. More torque. More enjoyment.

Yes... Would be great to see howvfast your going with a speedo!!

Isn't there a governor on the 4-stroke that can be removed? I heard of people doing something like that to get higher RPMs.

Seems like the four stroke would be better mounted to the back above the rear tire

Need help I have a bullet train 40.1 rode over 800 miles now it fills like it's vapor locking

OOf, I'd feel scared to have the battery mounted that low on the one with the electric start, let alone near where the exhaust is. that front tire kick up something metallic and that battery isn't going to like it.
