    You keep asking the same question and the answer is neither of these
    two kits is any good because of the crappy pocket bike gearbox. has no customer service.

    Unfortunately is out of stock on the Grubee 4 G kits.
    Hopefully when they get a new shipment they will have fixed the defective
    one way bearing issue that needed to be welded solid.

    Let me start by saying Thank you for your answer I was not trying to annoy you in any way I asked the question
    so many times for 1 reason, I would post the question in 1 part of the form, it would go unanswered I simply though
    I was posting it in the wrong part of the form.
    If someone would have answered me the first time I asked I would not have to keep asking the same question.
    Again I was not try to annoy you in any way all I wanted was a simple answer witch I thank you for giving me.

    Hi Samdallas214,

    Ask all the questions you wish, as that is the main reason for this site [information].

    As a kit supply company, I can't condem others products, however a little research on this site will supply you with information needed to make a wise purchase.

    I am sure you have heard the comment "You get what you pay for", and understand when you purchase a motorbike kit, the "lowest" price is just that. Of course some are better than others, but either you pay more to start with or spend money "fixing" the cheaper kits, in the end you normally spend more than you had planned.

    There are 3 companies that use American parts and labor making portions of the motorbike kits........Goleden Eagle, Staton, and EZ Motorbike.
    All three companies make their own American drive sytem, which appears to be the weak spot on the average Chinese kit.

    Hope this information is helpful.

    Have fun,

    Samdalas 214,

    I bought my kit from BikeBerry, 5G 4stroke New generation. I've had no problem with it at all. After the enitial break in time I've loged aver 120 miles on it and the only problem I've encountered was with the bike itself. I found this kit reliable. The only problem you might have would be in the lower bracket, Bike Berry doesn't have one with the kit and you would need to purchace it, that would take some resurch to find the won that will work.

    Dorouke what did you mean about the lower bracket and where did you get it? thanks for your help.

    Quenton Guenther than you for your help. I would love an American made kit, It is simply out of my price range.
    Thanks to an uninsured drunk driver I now walking ,I need a kit to get me to and from, I will never race it I will never get it above 10-20 MPH .
    So let me ask the question this way what is the best complete 4 stroke kit with a wide sprocket I can get for around $350.00 no more than $400.00 that would have to include any and all parts needed and shipping to Dallas Tx 75236 .
    What is the best dealer for around that.
    PS a scratch and dent kit would be fine as long as the Motor and or Drive system are new and work like new and it has all the parts there including the wide sprocket is all I care.

    Sorry, but the pocket bike gearbox on your kit is low quality and 120
    miles is no test of how good it is.
    The chain stretches and there is no adjustment to tighten it up and the
    bearing can wallow out.

    Let us know how it is doing when you have 1200 miles on the gearbox.

    Good luck! :)

    I doubt you will find a kit for $350.00 that will deliver the service you want. If you don't mind pushing your bike home once in a while, and it doesn't bother you to break down often, then the lower price kit is what you want. If you want it to continue to serve as dependable transportation, you will need to dig deeper into your pockets. Either you spend the money up front or spend it as it breaks down. The most dependable kits normally have an American drive system, as the drive system seems to be a problem for Chinese companies to master. If you do a little research on this site you will find the HS 49 CC and Honda 50 CC motors are very reliable, companies just couldn't get the power from the motor to the rear wheel without major problems. It is like buying a car with a bad transmission, no matter how well the motor runs, it still won't get you down the road. One major difference is you can pedal your bike home instead of calling a tow truck [LOL].

    Of course all this information will most likely be "tossed" aside in favor of price, however we will be here to offer help, understanding and fixes when you get your new kit.

    Have fun,

    The lower unit is the pedal crank. I welcome direct challenges on this site, it allows me the concerns of what to watch out fore in the future. I am well aware of the bearing situation and 1,000 or more miles is the true test of mechanical aptitude in these still experimental bicycles. I believe these challanges will spur further accomplishments in the future of motorised bicyceling. I hope the solutions will be freely shared among the community. I still think getting started without spending a fortune on this passion is a start at least, the addiction will follow. It takes alot of hard earned money to purchace something you will likely enjoy. I would rather start out with a $350 4 stroke and go from there. A 2 cycle for ME was not the way to go, I had only problems, not to say 2 cycles are not good at all. I enjoy my 4 stroke and will in the future resolve any problems with it, frankly, I enjoy the challenges.

    BTW, I believe the 49cc 4 stroke 5G kit from BB is the HS 49cc, at least that is what I bought 5 months ago.

    That do not seem to understand I simply do not have $800.00 to spend, and I have no way of getting it, If I had that much I get an old junker or I would go electric.
    I have a choice either spend $400.00 now. or walk another year until I save up the money I make less then $8.00 an hour by the time my rent,electric and bus pass are paid for I have less then $200.00 to buy food clothing and so on and that's for a mounth . I'm a poor man that does not even have a credit card. Again I would give anything to have that kind of money.
    From what I have seen on ebay the gearbox can be purchased for $25.00 - $65.00. If I have to replace them every 6 month so be it at least I will not have to walk.
    You can even buy the gearbox's that go on the Honda kits for around $200.00 that would still be less the $600.00 most of the Honda kits start at $750.00+ and that was for a smaller motor, and did not include shipping.
    Thanks for all your help I thank I'll probably go with BB.

    BGF on Ebay did not do me well, you get what you pay for. Quenton, do you have any info on the belt drive trans? I can make one if I need to ,just will take a little reasurch. I would rather put money away now and purchace one than make one. I do enough of that stuff for a living. PM me if you will. I would like to hear about it.

    Hi dorourke,

    Just ask any question about the belt drive and I will gladly answer. Here are a few comments that may be helpful.
    We use a special belt [automotive wedge or AX series], not a typical FHP belt for EXTENDED belt life. We locate the automatic clutch at the rear of the drive for 2 reasons, first to support the clutch with 2 large bearings, and secondly to reduce the clutch speed. I mention these important details because when building your own drive it will make a major difference and determine your clutch options.

    We are currently doing a major upgrade to our website and when completed we plan to have the Q-Matic drive system shown in more detail and offer various parts of the drive for the DYI builder.

    More questions?

    Have fun,

    Quenton, wow what an idea to mount the clutch to the rear of the drive. I can see many favorable reasons to do that. I think you could even get less clutch wear if I guess right, it also makes more sence to mount the clutch with the most support possible. I will keep an eye out for your web site, thanks.

    SamD from what you state why don't you get a F/D that costs $150 new then you just need a motor. New honda 35 is $250 and you'll have a reliable fun ride. Cost is where you want it to be. Or look on the 4sale threads and buy a good used kit. Just my 2 cents, good luck.

    You might also contact the major motorbike companies and see if they have a test motor for less money. I also know some of the companies have returned motors with minor problems [stopped up carburetor, stripped threads, etc.] you could purchase at a reduced rate.

    We don't have any used motors in stock, however we have sold off the test and proto-type units in the past.

    We might be able to supply a Q-Matic prototype drive at a reduced rate, just need to check our stockroom.

    Let us know if you find a motor and we will see if we can help with some used test parts to make it fit your budget.

    I also know some have upgraded to larger motors and have sold the original 49 CC motor at a really good price [I have purchased the 49 CC HS 4-stroke motor used as low as $75.00 and as high as $100.00 in the past].

    Have fun,
