Great video, would like to hear the bikes engine and maybe a top speed on the bike. Really like the music and host. 👍

[@bikeberry]

Thanks for the support.

[@jackhoward444howard8]

I got 2 of these that work good after an extra 125 dollar clutch replacement and about 100 hour labor bike berry needs to redesign the transmission.

[@ronalddaub7965]

I put the same engine on a 24-inch bike and it's geared really high but it rubs directly on the tire anyway it will go 33 downhill and the rest of the time it's a slipping because the clutch needs weakr springs,, or I should put it on a 26-inch bike other than that it uses a lot of gas.. because it's slipping all the time unless you're wide open down the road it needs to be geared lower and it wouldn't hurt being direct drive just saying buy the 50cc

[@ronalddaub7965]

@@jackhoward444howard8 it seems that people can do their own engineering as far as sprocketts but these little engines most of the time are geared way too high and that's not the fall of anyone but who installs it but if you're giving a sprocket you're going to put it on I get it sometimes I just deal with it the way it is that's one bicycle you need the pedal sometimes to keep it going

[@ronalddaub7965]

I added an extra gas tank just so I wouldn't run out going across town that was Little engines use a lot of gas unless they're geared right plus that tank isn't that big I guess that's why they sent me two

[@suanneackerman2501]

On a Hyper Urban 700c bike, it's either this, or a complicated pocket bike motor install in the frame, or an expensive e-bike kit. It looks more stable than I had thought, though, I thought the two end holes were supposed to match to the two little holes at the tail of the bike frame lol. This video helps alot.

[@meranberwyck7775]

DO you have a similar install for a 24 inch bicycle?

[@davesyrette906]

Hello. I love your videos. I need some help . I have a 49cc big bore pocket bike motor and I want to hook up a kill switch. We have had 3 different kill switches and they all don't work when we plug them in to the motor. So something is wrong. There is one wire coming from the motor and I am assuming it is a kill switch accessory wire. It has two plug in ports so my kill switches all plug in but do not stop the motor. What am I doing wrong. Please help.

[@ForwardObserverWarningOrder]

Thanks for the great video! I’m into electric bikes, thinking about delving into the motorized bike world… looking at building a highbred. I built a highbred propane, electric bike about nine years ago. I used a small propane 40 cc motor from a Weedwhacker, driving the cranks, installed a 1500 W geared front hub motor, and a 1500 W direct drive rear hub motor. I eventually dismantled it couple of years ago and I’m looking to rebuild a similar one. I bought some drivetrain parts from you all a few years ago, looking to purchase another small four stroke, and a freewheeling crankset. Any suggestions on a small 40 cc four stroke?

Hey bikeberry make this kit to be installed on a fat bike. I have the Micargi slugo SS. I tried with a normal 4 stroke middle mounted but with the tires being so wide, the chain scrapes the tire, also it didn't line up so I blew the engine.

[@jub369]

A HuaSheng 142F Kit will fit in the middle and work, just put the supplied bracket backwards move the engine as far left as possible and boom, this is how it is done on OCC Schwinn Choppers

[@ronalddaub7965]

Hello, I have just installed my 49cc big bore pocket bike motor and the carb is leaking. I have tried doing reasearch on this issue and I can not find information for the same carb I have. Do you have any ideas of where I can find any information on this problem.

[@limowmotoole2189]

Chances are your float is saturated in the gas tank itself, it’s made of plastic and can fill up with gas and loose the ability to float up to cut the gas supply off and make the carb overflow.

[@EdmontonRails]

Nice to have an installation video. Just wondering if this kit would work on a mountain bike that has a gear set on the rear wheel. It is on the opposite side of where the engine would be mounted.

[@MrFreth]

yes. It allows you to use pedal assist for greater speed or hill climbing capability.

[@suanneackerman2501]

@3:55 - looks like the plate only needs a couple mm on the axle. Probably not more than a cm. Idk if slack could be taken from the opposite side or not.

[@jackhoward444howard8]

I opened up the second transmission it has red grease on the vulnerable areas and there are many metal flecks on everything I'll clean it before reassembling. The drum for the clutch was crooked in the transmission tried to remove it's stuck hard.

My guess is never. You don't see these kits anymore. They probably weren't any good. They probably have a fatal flaw. My guess is the clutch bell is too weak to handle the torque from the motor.

[@Miklalo]

How many miles do you get with this setup? Can you add a bigger gas tank? How fast does this go?

[@antonisautos8704]

I built a bike for a friend with the exact same engine and wheel size. His does about 30 mph and he can go about 100 miles to a gallon of gas. That tank is quite small so it's best to put a basket or rack on the bike to hold a gas can, that tank only lasts maybe 15 miles maybe 20, since it's like 3/4 a quart of gas.

[@Miklalo]

antoni travels okay for the information this was very helpful 👍🏾👍🏾👍🏾👍🏾👍🏾

[@scooter979represent]

When I was selling the friction drive setups I could get a cruise of 28-34 and a max out of 40 but the small tank would travel on average of 40miles which is not bad at all for the size of the tank.unless you are in the country and need a bigger tank. But with this setup it would be easy to get a back up rack mount gallon holding tank.

The mount to the bike seems a bit chintzy to me. If it were stronger i would definitely consider buying

[@alexhickey5633]

Still tho a 38cc 4 stroke has weight to it and being a few inches out from the frame creates a nice bit of leverage and then the torque from the engine itself on top of that. To me it doesnt seem sturdy enough

Being perfectly honest man i wouldnt trust it. A thick billet aluminium mount would be my preference

That's why your expensive U-lock goes around your seat post, through your rear tire, and around a permanently fixed rack that can't be easily removed. Although with a battery powered grinder, a thief can cut though almost anything if they are willing and determined enough to spend the time.
