What Customers Are Saying
I got my 49 cc 4 G T back in March of 2012.
I love it. I ride my bike 30 miles one way to work everyday. I have over 2000 mile on my engine.
It still works like the day I got it.
The technical support I got from Robert over the phone and vie E-mail was awesome.
Everybody stops me and ask me about my bike.
They all love it.
I purchased this kit and have been running it for over two and a half years now. This is one VERY SOLID engine kit! The engine just keeps going and going, the belt drive transmission is solid (I keep using that word for a reason . . ), it has remained quiet and very little maintenance has been needed (change the oil, readjust the chain, that has been it so far). The power of the engine has not faded even so much as a little, in fact, after a break in period it ran better than at start-up. Still starts with one or two pulls of the rope. If you build one of these, be sure you put it on a bike you really like because chances are you're going to be with it for a long time! Solid engine, solid transmission and chain drive, I put it on a solid bicycle . . . it just goes and goes, and sometimes it goes VERY FAST! 2 or 3 HP isn't hard to find, 2 or 3 HP that will be around for a while is tough to find! However, not any more. I can vouch that this kit is definitely worth your hard earned cash. Be patient with it, install it correctly the first time, take care of it (and don't ride like a maniac) and this will stick around for years to come! I have moved to North Dakota now, and it was in storage. I pulled it out a couple of weeks ago just to get it up and running. Just like all the times before, two pulls and off we went to the amazement and fun of all who watched! Even after all this time, just like others who have put one of these together, I still get asked about it, offered money for it, etc. If you are looking for a commuter substitute (and live in an area you can ride without getting run over!) THIS is a very viable option for you! BTW, this is my third review of this kit, nothing has changed, it only gets better. Okay, enough, I am going for a ride now . . . . . . . You're still reading this? LOL! Seriously though, if you considering this kit, I highly recommend it. Make sure you have got a big enough bike to put it on, check you measurements closely, when you are sure, don't be afraid to give this a whirl.
I changed to the belt drive 6 or 7 months ago.Was the best thing I ever did. The help over the phone was great. It solved some problems and made none. Fantastic.
Some other sellers are selling a cheap knock off of this kit. There is a reason it's cheaper. Spend the extra for a Grube kit. You won't be sorry.
Dianne was a joy to deal with! After getting the complete run around and being ripped off by another Vendor who claims to be the ONLY importer of grubee products..., I will be sending lots of business this way!
I purchased my kit well over a year ago and it works today just as well, if not better after break in, as the day I first started and rode it. I had some issues with the belt drive and one way sprocket, but Robert was a really big help in it all. I got a replacement with a different ratio and after running it, found it better anyway. I am running a beach cruiser with this on it and it pulls my 230 lbs down the road a steady 25 to 30 MPH all the time. Some folks like different equipment, that is okay. Go grab the stuff if you like, but with a little patience and a very small amount of upkeep, this kit runs and runs and runs! Want to go faster? Buy a motorcycle. This was designed to be fun and relatively safe as the hobby goes. I get stopped and asked about it all the time. I will definitely be sending business here for sure. Advice? Take your time, mind your measurements and do it right the first time. Don't be stupid, ride safely. Remember, it is a BICYCLE with an engine. But most of all, have fun! I live in Colorado and this thing tackles the hills fairly well! I still have to pedal sometimes, but when I do, it feels like I am pedaling something very light because of the engine's help! Quiet compared to most two strokes, don't have to mix fuel and oil, just pull up and fill up (I cried as I had to pay 67 cents to top off one day after riding to and from work for a week, 30 miles of city traffic), centrifugal clutch allows engine to idle when stopped. Continuing to go strong! New tires next season, LOL! Thanks Gang!
I have ausa shipplng address and from there sendinf on tome in western australa.
