    Hi,

    I have a very solid 20 year old pre-suspension Gary Fisher MTB set up right now for commuting. The bike has a solid set of wheels and a great set of Planet bike fenders. The bike is set up with 1.5 inch slick tires. I will put on a bolt axial on both wheels for safety.
    I think its ready to go for the engine mount.
    My question is looking at some pics it looks a little tight for the fenders.
    My other question is the engine choice. The RS or the tanaka 33?
    Fueling would be easier with the RS but it seems a lot of folks love the tanaka 33.
    And another question what is a bottle boost? Is this an extra gas tank?
    My setup would be very similar to Kevin Demello's set up over on the GEBE site. Kevin's bike is an awesome setup. Don't know what he uses it for but he said he has nearly 5000 miles on the setup.
    The only other thing I plan on adding is a lowrider front rack for some paniers.
    All questions comments and rants would be appreciated.
    Also, I have a strong set of wheels but what about just getting GEBE's rear wheel with the ring installed? And, is a quick release on the front wheel safe or should one have a bolt on axial?
    I have a long commute so I guess I will consider all options and opinions on a bike build.
    Again I am very new to this motor bike sport. Not trying to annoy anyone! Just trying to get the right information to do this right the first time around.
    Spending a few bucks is OK if it gets me from point A to point B on a motorized bike that gets close to 200 mpg.
    Thanks and I received a very warm welcome to this community and I appreciate that! Just looking to build a project and come out OK. So the more information one has the better off one is.

    Thanks

    Kevin

    I am with Augi on this one as well....

    They are very nice, and very knowledgeable people to speak to!

    They will be more then happy to answer any questions.... as they did for myself a few months back.

    The GEBE system is the greatest investment I have ever had for my bicycle, you will love it!

    Hey guys,

    Thanks for the warm welcome.
    Augi I will email you.
    And Mr. Dog I will post what happens with this build.
    But I will need a little time. My house and town got hit by a tornado all is well but am just a little shy of cash at the moment. But its only money after all! My family is safe and I can still work so it will happen.

    Sorry to hear about the damage,,, but glad to hear you are safe ! Material things can be replaced ! The older you get, [ like me ] the less material things mean, anyway !
    Good luck with the build & you will be glad you went with a quality kit.

    Sorry to hear about your tornado damage.

    When you get settled, I recommend the GEBE setup. I got it 4 months ago and I have ridden 2000 miles without any problems at all. It's performance has been flawless.

    I got the heavy duty rear wheel and think it was the right choice. Potholes come up so much faster that sometimes you don't see them until it is too late. Also all the motor weight is right over the rear axle, so there is additional stress on the rear wheel. I still use quick release on the front wheel and that works just fine.

    I have the Tanaka 32cc and runs flawlessly. I now get 32-33 mph on the flat and takes big hills easily at 20-25 mph. But be sure to mount an auxillary gas tank to extend range. I added a 1.5 liter tank to increase my range to 80 miles between refueling.

    Get the rear wheel !!!

    I totally agree with getting a new rear wheel when you buy the kit. Like I posted in other threads, the new rear wheel will come WITH the drive ring installed making your installation easier and faster. Best of luck and I hope everything turns out right.

    Hey thanks for the support!
    Well as far as cycling goes 2000 miles in 4 months? That's a lot of riding!
    Wish I could do those kind of miles on my pedal bike and I would give Lance a run for his money!
    Seriously I just have a lot on my mind right now and I will motorize my Gary Fisher eventually. I am prepping the bike right now. Waiting just for some extra cash to motorize this bike. I think you will like what I am up to!
    I am of course no genius just a guy that likes to ride around on bikes.
    Ya know I have a blog about my ultra cycling stuff this season and I just might post a link here with some pics of our tornado damage in our town.
    Heartbreaking really and my damage is just about all fixed but others are not quite so fortunate as we were.
    And really its quite hard for some to understand what ultra cycling on a pedal bike is all about. I am not an ultra cyclist. I did some long rides this season but its way out of my league!
    Well, to each his own. If your on any kind of bike not putting money in BP's pocket its alright in my book.
    Well for whatever its worth Viva la Motors!
    Its after all all about the motor as Lance Armstrong says!

    It's been awhile since I posted! Sorry...
    I will be getting the kit very soon. I do plan on just ordering the super strong rear wheel with the kit. Look, on my Orbea road bike I got late last year I upgraded to a super nice lite set of wheels. Cost? 1000 dollars with a set of ubber nice Conti tires! Lots of common sense on this forum so no doubt I am listening and want to have a smooth easy mount!
    The host bike is all cleaned up and ready to go. I will do some additional modifications after I motorize the rig.
    There is no right or wrong here but I have some ideas about gearing and such that I will get into after I build the bike.
    I hope its interesting to all of you!
    I am just experimenting right now and looking for pure functionality and simplicity on a bike that I will be commuting on 75 miles round trip.
    I am excited about this little project and looking forward to sharing with you what I come up with!

    I will be eagerly waiting to hear of your gearing ideas.
    I plan on buying a GEBE setup with the uber strong rear wheel when I can afford it.

    Good luck with your build!

    Hey all,

    I went with the Robin Subaru 0h35 engine 4 stroke. I think that this will meet my needs the best after consulting with GEBE on a lot of my issues.
    I have a light solid bike but in spite of that I ordered GEBE's super beefed rear wheel.
    This build will be a very very heavy duty commute bike!
    What do I know about motored biking? Zip. But I got some good advice and hope that I have spent my money wisely.
    Note that in life one gets what one pays for as in there is no free lunch.
    I will start a new thread here when my kit arrives and I start the build on my bike.
    I might also only post comments about this build on my blog for total editorial control.
    I am really leaning that way though...

    hi kevin, as a GEBE rider with over 30,000 mi I can say you wont be dissapointed i ride a 40cc tanaka and my wife ( quay1962 ) rides a 35cc robin whisper quiet reliable and the gas mileage is unbelievable

    Wow,

    Your some one I would like to talk to.
    I have my commute to work down to 64.5 miles per day!
    I did go with the R/S for fuel reasons and gave up a little speed but I hope this will work out well for me!
    The kit will hit my door step on Thursday the 30th.
    My comments about this set up will be on my blog.
    It's just easier for me to put pix up and to put my thoughts about the setup.
    I was on the phone with GEBE for well, quite a long time about my engine choice. I do believe that I got great advice. I am of the opinion that GEBE for what I need just builds the best kits. However, since I am new to this motored bike thing I will be quite honest with my experiences.
    My build will be quite routine however since my Fisher MTB is just an ordinary bicycle. It is high quality and effecient but ordinary.
    Lights, fenders and the whole nine yards to get to work and back!
    Here is a link to my blog: http://thekettle-morainebiker.blogspot.com
    Just cut and paste in between the xxx tags into a new browser and you will be linked to my blog.
    Nothing but ultra cycling stuff on there so hopefully not a bore...

    The kit is mounted and I did a short 44 mile ride today in the Wisconsin cold and headwind.

    Isn't it wonderful how a 44 mile ride can be described as a "short" ride!

    I have the GEBE kit with the Tanaka 32cc engine on a 15 year old mountain bike. I have ridden it on lots of 50 to 60 mile rides in very hilly areas and the rides were "short" and "easy."

    I was and still am an avid pedal cyclist, but pedaling 40 miles in very hilly areas is a long and difficult ride for me and the longest big hill ride that I would want to pedal in a day. By comparison, with my GEBE I have ridden 120 hilly miles in a day and it was not hard!

    Hey Virginian,
    Ah, the land of the greatest American IMHO Thomas Jefferson.
    I was seriously going to get that Tanaka 32cc 2 stroke but Julia from GEBE talked me out of it. It might be a bit slower but the fuel hassels just don't exist. I just in the end did not want to bother with mixing oil in my gas. Its cooler to pull up to the gas station and put in a pocket's worth of change into the gas tank.
    I am motoring along with an out of the box robin 35 with some pedal assist at 26 plus miles per hour average speed in some very hilly Wisconsin country!
    The top end with the standard gear on the flats is 32 mph.
    When the motor is broken in I plan on getting the high way gear which I am told will give me a 10% speed increase and better fuel economy. So an average speed of 29 mph or so? Its simply fast enough. Its a great kit.
    Tell me. How did you attach those bags to the rear of that mountain bike?
    Your setup is much like mine. I am very interested in how you mounted those bags on to that bike.
    The bags on your bike kind of hide the motor and attracting as little attention as possible is the way I want to go. Cops have low IQ's so its best not to attract their attention!
    Thomas Jefferson was a big fan of the second amendment to the constitution just for the retarded police man.
    I mean I have been reading stuff on this site and its like gas is 3 bucks a galleon and some states just make it tough to get around. These bikes are just a great idea for basic transportation.
    In Wisconsin fortunately all you need is a drivers license and a motor under 49cc and you are good to go.
    I have been motoring around for the past few days on this bike and see absolutely no problems with them at all. Its a great idea...

    Mixing oil into gas

    I guess I have gotten used to mixing the oil and gas so it is not too big a problem. I have a 1-gallon can and I just add oil as soon as I buy new gas.

    I can carry quite a lot of pre-mixed gas with me. The stock tank plus auxillary tank gives 80 miles of range. Two MSR bottles in water bottle cages add 50 miles of range. A large 1.5 liter MSR-type bottle that I can carry in my panniers adds another 55 miles. Total range is thus 185 miles. I also carry small pouches of oil that I could mix on the road giving essentially unlimited range. Photo shows it all.

    Top speed on flats

    I think my top speed on the flats is about 31 mph. I also pedal assist.

    I worked hard at making sure I measured it accurately. I checked my bike computer calibration by riding a 5-mile measured course and it was right on. Then, I rode "flat" pieces of road in both directions and took the average. The reason for averaging both directions is that even tiny grades that are not apparent to the eye will affect speed. Also, even light winds make a difference depending on whether they are head winds or tail winds.

    I can maximum average speed on rural roads is 26 mph if I really push it, but 25 mph is more common. Even though top speed is over 30 mph, hills, turns, potholes, curves, and stop signs all cause the average to be well under the top speed. In urban areas, my average is usually about 20 mph because of all the places that I have to slow down. Still that is really fast for a bike!

    Attaching pannier

    Note that I have only 1 pannier (right side of bike). On the left side I have mounted an auxillary gas tank.

    It was some effort to attach the pannier, but I absolutely needed some carying capacity for long rides and for errands. For grocery shopping, I also use a backpack as shown in the attached photo.

    The pannier is permanently mounted. I took an ordinary bike pannier that had a stiff backing. I drilled w holes in the GEBE motor mount support. (This requires a drill bit for steel.) I cut a 12" piece of aluminum strip (1" x 1/8") and drilled 2 holes in it and mounted it over the stiff pannier backing and then bolted it to the motor mount support. I also bolted into the top hole another 12" aluminum strip horizontally to add additional stiffness. It works pretty well.
