    I am thinking of mounting my grubee 4 stroke on a Felt MP cruiser. Has anyone got experience of mounting a V-mounted 4-stroke on a Felt MP cruiser. Or any other Felt Cruiser.
    The MP seems good because it the strongest bike available with so much included in its price such as mudguards, rear & front rack, fat arsed sprung saddle, dynamo hub and lights. 12 guage spokes and really fat tyres Unfortunately it has a 3 speed hub with coaster brake which I think is a nuisance for a motor. I doubt if the hub would fit the sprocket wheel and it has no front brake which is a pest as well. Otherwise it is perfect. Any ideas? Picture attached.

  2. The one pictured is a single speed.
    At any event,that would definetly be a great candidate for a frame mount 4 stroke.

    Your right

    Thanks Large, Last years model is a single speed but 2008 model is a 3 speed hub. It's a great bike built very strong cos I've checked it out but what a shame about the hub plus the tyre and mudguard would get in the way of the chain I reckon. Very narrow clearance between rear stay and tyre/mudguard. Pity they don't just have the bolt studs on the front forks and rear stays for V brakes. I don't think the bike could take a 4-stroke. Their other Felt cruisers are very robust but have similar hub & brake problem. Here are detailed photos I took of an MP Felt in the shop in 2006.
    It also has 12g stainless steel spokes which is a great help for strength. A nearly perfect bike but sadly not quite good enough.

    It sure looks to me like that bike in the photos above has a front drum brake? If it does not then what is the brake lever on the handlebar for? If you do a search for Felt cruisers here I'm sure you will come up with several with motors, I seem to remember at least one in the photo gallery that has a 4-stroke.

    John, Sweet looking bike. It looks tight between the rear wheel and the rear frame. I had to trim my fender to make the chain fit. Your fender may be too nice to trim, Your inner frame looks like plenty of space. It looks like more room than mine. Rear mount maybe?

    Irish John It Is Good To Hear And See That Someone Else Is Considering Using The Felt Bikes For Motors I Have Done Over Thrity Felt Bikes And It Can Be Done The Tank Can Be Sealed And The Motor Mounted W/out Welding And Destroying The Paint .
    The Rear Srocket Will Have To Be Milled Out To Fit But That Can Be Done On A Drill Press W/ A Milling Bit Or A Machine Shop Not A Big Deal.
    Also You Can Get Away W/ Out The Chain Tensioner The Felt Bikes Are Not Easy To Build But They Sure Look Good And Run Good .

    The MP is the one I like

    Thanks HB, It's the MP I like best cos you get a lot of bike for the price (mudguards, racks, good saddle, great handlebars, a dynamo -prob pretty useless chinese one - and it's ultra heavy duty and well made. If you have any experience of putting 4-strokes in the MP frame I really would like to know more. Maybe a separate thread with lots of pics and close ups. I can't see how going w\out a tensioner would be OK though - I find them pretty essential. I'd really love to see MP pics of how you mounted the engine tray and the rear sprocket. How frequently do you have to service those coaster brakes and what sort of headache is involved? One hing about simple disc brakes (i.e. non-hydraulic ones) is they are SO EASY to service and keep running. I'll look at your gallery and see if you have them up in there HB but a special thread is required cos lots of people would want to know about these bikes. See attached pic below - I reckon a 4-stroke can't fit in the frame.

    You're right Graucho - there is more room between the seatpost and downtube but less between the bottom bracket and the top tube. The critical bit in the 4-stroke is height moreso than length and the Schwinn has a convex curving top bar which accommodates the height just where it's needed. Just where it's needed is where the felt top tube curves down towards the seat post tube and this is where I reckon the 4-stroke will be unable to fit. There are other problems too that I've mentioned elsewhere.
    It would be great if Felt built a bike frame specially for grubee 4-stroke kits and Whizzers etc cos their quality control leaves the Schwinns for dead. I think the frames are that hydraulicly formed alloy which is a really high-tech method but very strong technique for making light and strong frames.

    Saw this on the web today. It's a motorcycle mfg that's making a 2 stroke powered bike out of the Felt's. AWESOME detail. I called them and asked what was up with their pricing and apparently the $1999 price includes everything (which it should). They told me the motor was rubber mounted which isolated the normally crazy vibration those 2 stroke put out. The front mount is made from billet (what, you mean its not stamped chinese pot metal?). And the fuel tank is the frame.

    Check them out....

    I guess I don't understand why the mods are giving the Firebike kid a hard time when at least the stuff he is pimping has some originality and the pictures of the bikes are at least real but nonetheless Spam always gives me gas. WhyNot, if you have something to sell just get on the vendor list, it doesn't cost anything. Otherwise you are just looking like a fool. Those bikes on the Ridley site are nothing to write home about really. Anyone can go down to the Felt store and buy one of those bikes and bolt on a HT kit (which is way less than zero emissions I am afraid) and do a tank job for less than half that cost and have fun doing it. No doubt you will sell some to those that are enamored with the whole idea and don't have any mechanical skills to do the former themselves, but those are not the type of folks you want to submit to the HT experience in my book.

    MP from Ridley?

    They posted new photos that show the front mount better. I emailed last night and got a response late today that said there are "dual rubber pillows" on the back providing "great rubber mounting". No photos attached, so I can't say what that means.

    If you watch the videos, it shows the front mount in action. But the way the motor moves around, I don't think the bipe would last long without some sort of support brace back to the motor.

    Hot Wheels Felt is a go!

    my bike 2.jpg I just mounted an HT motor on my Felt Hot Wheels Anniversary bike similar in shape to the MP. I liked the MP too but found my baby for about the same price on Craigslist. I got the #16 bike. The motor mounts low to the bottom bracket but didn't have too many problems. Yet, even though this model has an aluminum frame, she's a big heavy tank. The MP model is a steel framed bike and must be a real monster to ride but steady for sure because the forks are so dang solid. Furthermore, the chain runs awfully close to the tire but I have yet to have any difficulties with it just yet but I only have 7 miles on it because I just started the break-in period.:cool: The pic is from last week when I was still piecing it together. I'll get more when I get home from work in the morning.

    I started this thread ages ago but even now there's not much info about 4-strokes on Felts. I've decided that a 4-stroke HAS to have front suspension because I've tried rigid forks and they were just about OK until I tried springer forks. The Felt Heritage looked like the best bike for a frame mounted 4 stroke but I researched it and found the frame too tight for the engine tray. The MP would be too bumpy with those rigid forks and the 3" quick brick tyre would have to be replaced with a 2.125 tyre. The best frame I've used so far is the Schwinn D7 but the price in Australia is a total rip off so I'm looking at Micargis to replace the Schwinn but they probably have problems.
    The Schwinn in Australia has to have front V-brakes in order to be legally sold and that's another must. A 4-stroke without a good front brake is a total death trap. The coaster brake might stop a little kid but it wont stop an adult even if you stand up on the pedal. So many bikes look so good but fail completely on the brakes or the forks. I would like to dedicate the remainder of my life to a campaign to consign the coaster brake to the dustbin of history.

    Hi Irish, check out member 2lazy2pedal in the picture gallery he used a felt taxi with the 3" tires, still a 2 stroke though.

    Thanks Hotrod but I can't find him on this forum & I looked in the gallery as well. Can you post the URL to it please?
    You can run 2-stroke with shifter kit on a 3" tyre no problems but a straight chaindrive standard mount gives tyre slapping problems.
    See this pic of someone's Felt - beautiful with an NV hub I think.

    Felt MP With 4 Stroke

    I successfully mounted a Grubee Whopper Stopper 4 stroke engine (Stage II kit) to a Felt MP.
    I really like the frame geometry on this bike and my other motoredbike, the Felt Iron Bolt. Things to consider when building the MP: 1) Get rid of the rear wheel. The stock internal shifting Nexus hub does not allow for BMX style chain tensioners to be installed. BMX or RMX chain tensioners are mandatory on this bike, as the motor tends to pull the axle forward. This causes the pedal chain to go slack and fall off. Since it has a coaster brake, all of a sudden you have no brakes. Also, if the rear wheel goes out of alignment, the motor chain will rub on the tire and eat it up. Just get a generic 26 inch coaster brake wheel and some BMX or RMX tensioners (such as Diamondback part number 57-18-502 or 57-18-500) you are all set. 2) The newer Grubee Whopper Stopper Stage III (Honda GHX50 Clone) kits have a 3 piece wide crank kit. The wide crankset is necessary so the pedals don't hit the motor. You can adapt the 1 piece bottom bracket on the MP to the 3 piece crankset using an adapter kit. Be sure to ask about this when you order the motor kit. The only trick is to use lots of red Loctite on the threads when you assemble the crankset. Use plenty of grease inside the bearing cups, but don't get any on the threads. I made the mistake of assembling everything with grease the first time. The vibrations shook the crankset parts loose, and I had to clean the grease off and reassemble everything with Loctite. 3) You may have to weld the chainring to the spindle. The chainrings have a goofy setup that requires you to pound a pin into a hole to tighten the chainring to the spindle. I couldn't get the thing to sit tight, so I did a few spot welds to make sure it doesn't come loose. I know it will be a pain if I ever have to take the crankset apart, but I don't want the sprocket to slip on the spindle and lose braking power on a big hill! 4) A front drum brake would be nice for decent stopping power. I am going to see if I can get a front drum wheel from Felt. -Erik

    Hey Madbiker1, nice job on the Felt. I have a HT on mine and have not experienced any of the problems of the drive wheel moving forward nor the tire chaffing. I also like the frame as it feel sturdy and so far with 600+ miles, no problems have developed. For my front brake, I picked up a Sturmey Archer Dynamo brake unit for about $57.00, plus shipping, it was an additional $33.00 to have the bike shop lace it for me. Might be cheaper in the long run compared to one from Felt. Please let me know what kind of comfortable cruise speed you are getting out of this motor, pretty cool!

    I'm glad someone has at last tried a 4-stroke frame mount on this bike Madbiker1. I've seen 4-strokes on other Felt cruisers but not this one. It seems a shame to swap the rear wheel cos it has 12g spokes and a 50mm wide rim. In Australia the MP came with a front Dynamo coaster brake combined in one hub. It also had a Smano Nexus 7 spd rear hub. Too expensive to throw out. It is possible to fit a chain tensioner on the chain stay and even possible to fit a spring loaded one as per the many shown on this forum. The mudguard has to be cut away but removing it as some have done strikes me as just devaluing the bike cos mudguards (or fenders as you call them) are essential if you want a dry ride. Short sports mudguards a waste of time.
    I've looked closely at the MP and you can see that the clearance between seat stay and tyre is difficult but not impossible. 2 strokes have been mounted successfully and they have the same chain. You need a 48T sprocket and special clamping gear for the Nexus 7 spd. I can supply that to anyone who wants cos I make the clamp from 318 marine grade stainless with 2 ply rubber cut to fit and 48T sprocket drilled to fit as well. The good thing about the hub gears is that you can change when stationary.
    I think that the tendency for the engine to pull the axle forward on the horizontal dropouts is easily overcome with a bit of skill.
    The pedal chains often come off Nexus hubs because of one reason I spent ages trying to figure out - the back sprocket is often assembled the wrong way around because it can fit both ways but only one is the correct way. The exploded drawings of the Hub on the Shimano website do not show clearly if the convex or concave side of the sprocket should face in or out. Only one way works and the wrong way causes the pedal chain to come off which is hard to put on again without undoing the whole wheel assembly. Shimano don't mention this in their manuals.
    The MP is an incredible bike and built like a brick dunny (outdoor privy) and will last many decades I reckon. The lack of front suspension is a disadvantage but a softly inflated front tyre will certainly assist on bumps.
    Your tensioner brings the top & bottom of the drive chain very close Madbiker.
    The other problem with the MP is fitting the tank so it looks good. Rubber belting seems a good material but fixing it to look good is a challenge. Looks are everything to a proud MBc member!
    Can you post more pics of this build cos it's a first and well done Madbiker but you do need a front brake .
    I'm about to try brazing V-brake bosses to seat stays with Mapp Gas and Sure Fire Torch so stand by for the results. Discs are my preferred brake but a V-brake sure beats a coaster if you need to throw out the anchor quickly.
    The MP was $1200 Aus last year but they've stopped importing it and Felt are stopping making it. That's the trouble with Felt - all silly poems and not enough spec data on their website and catalogue. They must think the market is full of pre-pubertal idiots with access to Daddy's wallet. Maybe they are right. Also Madbiker the one piece Grubee crank would look much better on the MP than the 3 piece. Nobody can get them just now because Grubee are pushing that 3 piece with short crank arms but soon the suppliers should come to their senses and order them in. The 3 piece has its purpose if you have a cruiser with a 3 pice BB but that is the only occasion I'd ever want to use one.

    Thanks for the lead on the hub. $56 sounds like a good deal. I'm getting about 25 mph with the 56 tooth sprocket. I think it would go faster with a smaller sprocket, but I'm more concerned about taming the hills here in Colorado. I would probably never ride a bike here if it weren't for the motor!
