    Bike is discontinued by Raleigh, with MSRP of $409 + or - a buck or so. I was put on to bike by one of our amigos here.

    I found new 2006 model (Root Beer Brown) for $249 scoots via Erik's bikes in MN. He has outlets in WI.

    Bike style or configuration is equal to Specialized versions and others at way lower buck and is CF also. It is perhaps best CF buy but not as good as a Rans, but then, who would motorize a $1000 Rans - besides me?

    Am sure you can get other dealers to sell for lower price.

    Worth it.

    Nice bike; CF (Crank Forward), front suspension, decent components, 24-speed trigger Shimano shifters.

    Machine is very GEBE compatable.

    I put a GEBE wheel with Armadillo on rear and may put engine on tomorrow. Will post pics at some point.

    Gruv 2 Pics

    Need to connect throttle cable and kill button. Fasteners are hex-head SS: .25 -inch for engine strap and 5mm to fasten rack/safety bar to engine support mount.

    Handle bar grips not pushed on and the Sinz brake/throttle is a bit tricky with the Quick-Fire Shimano shifters and brake levers that come with new Raleigh Gruv 2 but is comfy and well placed.

    Comfort style handlebars are lowered to get grips set just above knees - ala Rans CF style - to gain leverage on inclines/hills, when not motoring, which is most of the time for me.

    Fenders later, along with small screws to hook or to hold belt, when detached from drive ring, to keep from fouling spokes and axle and to look tidy.

    However, I should be fishing for steelhead...

    Ahh, Steelhead.... and some people think that these bikes are an obssesion. I don't chase the steelhead anymore, but there was a time when they were the most important thing in my life.

    Well I Understand

    Like the fish, twice a year I take a run up the river and have a ball.

    Been doing it since '83. Prefer it over hunting. No people or very few and WI's Bois Brule River is very pretty, for non Alaska river.

    Wish I could ride to fish like when I was kid.

    Finished bike

    And new place for the kill-switch. The little wire attached to metal is ground connection when bike is chained while I am in tavern, to thwart pranksters and thieves.

    Thing is the coolest bike I have motorized yet - will have to stop this habit. Not as comfy as bent, and maybe required some picky fabrication (bent was a snap to motorize) but the Guve 2 is way fun, way-way fun. Its CF feature makes it a flat-footed bike, so tall folks don't have to sit so high the balance is off and have to lean bike at stops, and so on.

    Too bad it is not spring.

    If you do not have one, find and buy it fast (discontinued) and get the seller to drop prices to $250 or so.

    Maybe the best rig yet to use with little motor, IMHO.

    I don't know exactly how to describe the look of that bike. It looks comfortable, practical, and graceful. I think that covers most of it.

    :cool:Hive, i went down to EKI CYCLERY to check out their bikes. lo and behold, there was a "root beer"-colored 2006 RALEIGH GRUV 2 on the floor. I sat on it, and liked how my feet planted flatly on the ground while sitting.
    I didn't like the light-duty easy-on axles, especially the rear one.

    i believe it'd make a good candidate for my MITSUBISHI 2.2hp engine and STATON gear chain. since the MITSU engine is cranking 29.5mph @ 8700 rpm on my 20" DAHON, theoretically the RALEIGH should be able to reach 41mph with the same engine/gear chain setup/rpm.

    I was off hunting steelhead.

    I use a GEBE rim and 9-inch axle from GEBE also, for rear wheel. I just switch it from bike to bike.

    I kept the Raleigh front wheel, but may change it.

    If the bike is priced right, jump on it. It is good machine and can be souped to do what you need, but is more inclined toward GEBE set-up.

    Speed is not my forte, but I suppose it might approach 40, but be careful.

    :cool:Of course, i could gear it down for more low-end and safer speeds.

    A Throttle Comment

    One item that required minor custom work was the Sinz brake lever I use as a throttle and how it fits with the Shimano Quick-Fire shifter. The Sinz clamp needed to be filed to be compatible with the bulky shifters and be in efficient riding position position.

    Outside of that and drilling out the rack attachment on the seat-post tube for the side rack (or racks as I may add one opposite and remove the center strap next spring) and a longer throttle cable, this CF bike was a snap to put together. May also add a copper elbow and silicon hose "muffler" in spring. If I can locate appropriate hose. The Tanaka 3300 is not too loud, but quiet is nice.

    Here is larger pic.

    :cool:Hive, with your seat so high, are your feet still able to plant flatly on the ground?

    Seat Height

    Actually, the seat looks high, but it is not, as the pedals are more forward, so the feet sit on ground flat, easily.

    That is the the idea of a CF geometry and also makes for more powerful pedaling without need to stand on pedals, although that is possible.

    The oddly curved unisex bar and low bars (I turned them down a good 6 inches) makes the seat appear high. Am guessing it is about 3 inches lower than on my cruiser frame or a MTB.

    Moreover, the T-3300 engine sits lower than the 4-cycle did, and the seat is also lower, compared to engine height. It was necessary to tilt mount back a bit more from vertical to keep engine from rubbing against my rear-end. On the Trek cruiser, seat was just above or even with top of higher engine and the mount was closer to vertical. It all adds up, or down, depending on which way you look at it

    When I stop, I just drop feet to ground and sit there until time to move. Center of gravity is way lower now and sharp turns are much easier to control.

    On cruiser, I had to tilt bike and "tippy-toe it" otherwise. Very comfortable arrangement.

    If I have time, will take pic of my bod mounted on bike to better illustrate it.

    Crank Forward

    I was going to enter pic with my feet on ground, but decided that would not explain the unique crank forward (CF) geometry. Here is better description, I trust.

    The pic should help explain why one can easily place feet flat on ground with crank forward design, and why power pedaling is easier with no standing.

    The Red dots indicate the position of DF (Normal MTB geometry); the line or plane connecting the green ellipses indicate the CF.

    The guide being the extended leg with heel on pedal is identical for each.

    As the seat is lowered and the crank is moved forward, the legs drop, in this case approximately 5 inches. More than enough to touch ground easily.

    The other bonus is that with the hand grips set just above the knees, the rider can "pull" the grips to assert substantial leverage to the crank, and not have to stand, unless absolutely necessary.

    This design is the geometry of the future. It is a wonder someone did not figure this long before.

    Frankly, after having put a GEBE set-up on a cruiser, recumbent and the CF Raleigh, there is no question in my mind that this frame geometry is the best for general cruising or for those who prefer a little occasional help.

    It is a shame Raleigh dropped this model.

    The Raleigh Gruv II Crank Forward Update

    This is third spring with engine on this bike. Never made it past one year in past.

    the combo works for me.

    In fall, I remove motor and hang bike up. The long rear axle allows for double nutting the rear, with the mount in between the nuts.

    Do the storage gas drain drill and wait for spring.

    Installed engine and attached throttle cable and put a few drops of oil in plug hole and worked piston a few times.

    Filled up carb and the Tanaka kicked over without a cough.

    Cannot get any easier than that, No mess, no fuss. Clean and fast.

    BTW, take a look at the Rans Web site. they have a couple of new bikes that look to be "freight" carriers that might be very applicable for some users who do lots of travel and camping on their bikes, but would like a motor assist on occasion with motor in front.

    Glad to hear that you're still putting around.

    it IS a shame crank-forward isn't offered in the "common" brands. it's so obviously the right geometry for a grown man.

    hive's right: comfortable at-rest posture, no standing needed for power, better push applied to the pedal & excellent horizontal pull on the grips...

    Cranks and Crank Forward Bikes

    Hi Van and Augi,

    Been showing friends Van's vids of trips in "Palin Place." They cannot believe their eyes.

    Yes, Augi about Rans and CF wheels the best of both worlds. Seems fewer CFs being made lately, when opposite is best option.

    Too bad Rans bikes are so spendy, but I guess they planned to cater to limited market.

    I know from SR's information, their Fusion requires some work-arounds but do not know about the other models.

    He is still riding it, I believe...but he commented the unsprung ride was hard on bod. That got me looking at the mountain version with shock forks and more upright. Still have not decided to buy - at $1100 plus scoots is big bike money.

    Been mostly hunting steelhead but today the bike goes for run, with motor on.

    Hi Bob,

    I saw "your" bike, the Raleigh in a bike store in Tustin, CA recently (2010).
    The owner wanted too much for it, IMO, somewhere around $400 if memory serves me. I rode it but didn't care for the feel of it.

    Then, I really lucked out. I happened upon a Fuji Saratoga which is a CF bike with a step through frame. I love this bike! Only problem now is the GEBE throttle cable is too short as is the kill switch. I'm thinking about installing a brake caliper/throttle. I've never been crazy about the GEBE throttle or kill switch for that matter.

    Actually, Sick Bike Parts has a rocker kill switch they say is better than the button switch. Might check into that later. Being a woman and not very knowledgeable about mechanics, etc. I'm learning with the help of people on
    this board. Frankly I don't have a clue how I would install a rocker switch so for now, I'll just deal with the throttle issue.

    Been fishing lately?



    P.S. Sent you a PM a few days ago.
