All I want to do is get some help up hills

    Ladies and Gentlemen, I've spent ages searching this site and cannot for the life of me find a simple answer to this;
    I love cycling but am finding the Scottish hills a bit of a chore, all I want is some help going up hills.
    Everybody seems tied up in how fast they can go. If I want speed I'll get a motorbike. I have no wish to go at 30mph and I'm happy to pedal ( to keep my waist trim-ish).
    I don't mind if going up the hill is at 5mph (that's about all I manage anyway)
    To be honest I loved the idea of an electric bike but the range and battery technology still seems poor.
    Can anybody point me in the right direction to help me up some of these steep little hills?
    Many thanks

    Scotland, eh? Well, given your weather, a friction drive isn't the best bet. I have no clue what scottish law is like regarding motorizing bicycles - if it is much like english law, a frame mount is likely to get the local bobby with his knickers in a twist. Rack mount GEBE or chain drive from a small 2 cycle seems like a good bet. Depending on your bicycle, you might still be able to use a behind the seat tube jackshaft and a driven chainring/freewheel to continue utilizing your gearing through the drive chain.

    I've seen one rig with that setup, the driven sprocket and the jackshaft were mounted above the pedal swing path with a modified chain guard, and similarly down to the driven chainring at the crank. Alternately you might front mount the engine and drive ring/sprocket.

    What kind of bike are you riding?

    No problem

    If I were you I would look at the Golden Eagle setup (Gebe) Robin-Subaru EH035 with maybe the trail gear. You would go 25-30 mph on the flats and going up hills and some peddaling 15-20 mph. Gas mileage is around 160 per gal. The Robin-Subaru is a Great dependable engine 4 stroke. :wheelchair:

    While Oban notes a concern about the adequacy of batteries, I think we're jumping too quick to a gasoline solution to his problems.

    As I understood it, he wants to do most of the pedaling, and only needs some assistance with the hills.

    Correct me if wrong, but I think an electric solution may better fit his needs, in being less heavy and awkward when solely under pedal power.

    Scots law

    Thankyou gents for your quick replies.
    UK law says that any vehicle powered by an internal combustion engine is registered, insured etc, so its either loads of hassle/ go stealth or go offroad.
    I like the idea of a friction drive for its simplicity. It does rain a lot here, however I tend not to cycle when it's wet.
    I also don't have a problem with reverting to manpower if the drive is slipping.
    Would something like a Staton friction drive with a 25cc honda have any hill climbing ability (obviously with me helping)?
    The problem with the electric bike is range when hillclimbing - it seems very poor.
    Sorry I don't understand some of your American vocabulary, are you saying that some engines can drive the chain wheel (the one with the cranks attatched) so that you can change the gearing with the derailleur? That sounds ideal.

    You're not asking for much.

    A 1.1hp Honda or Subaru engine with Staton friction drive and 1" friction roller will suffice.

    How aboot a 25cc Subaru Robin set up as a friction drive with as large a knurled style roller as you can find that will alow you to roll you up those hills at whatever speed you feel most comfortable with. Keep it all as light as possible. You won't get any top end however so across the flats and down the hills you will be carrying the extra weight of the system but if you are willing and want to pedal anyway the extra weight will not be too bad across the level and certainly no harm on the downhills.

    Mabman, you mean the SMALLEST friction roller, right?

    No No No Youre All Wrong...

    :taz: ha...just kiddin.

    Hill climbing or wet conditions are not a friction drives forte'.

    This fellow enjoys pedaling just wants a little assist up the hills so a light weight chain drive with freewheeling capabilities is his best bet.

    The Staton Robin 33.5 is a bit less pricey than the GEBE Robin , freewheels for pedaling, can be geared lower, is lightweight and chains are more durable than belts. Shipping belts to Scotland could be a drawback, chains are always available.

    Thats my recommendation.

    Get a GEBE Tanaka 2 stroke a 32 or 40 cc works great in the rain and also starts up very easy. light weight good quality super easy install. you can still peddle if you want to.

    Yes. I don't mess with friction anymore and I got mixed up. Thanks for setting me straight!

    I agree with this statement

    and as you have stated -- you don't plan on riding in the rain anyway

    my little Subaru 35cc -- 1" friction roller

    get's me right up hills -- with some pedalling

    hills that I used to -- not enjoy at all -- now are fun

    as I ride that THING

    Thanks for all your help guys, for simplicity I'm minded to head for a friction drive, Saton do one with a 7/8" roller which must be even better than the 1" for hills.
    All I need now is for the dollar/sterling exchange rate to change in our favour
    Kind Regards from rainy Scotland

    there you go -- MINE HAS TURNED OUT TO BE -- STRONG

    I said the 1" roller -- but the 7/8" will be more than fine

    which engine are you getting ------- Robin 35cc ?

    if so -- top speed should be around 20 mph

    have fun as you RIDE THAT THING

    That certainly is being thrifty for sure. But don't wait too long because you are only wasting time from now on by not doing yourself the favor of just getting one and having at it! Good deals can be found on the parts if you dig deep enough, or know the right place to look to begin with. I may be able to help you out with a motor at least to get you going if you are looking for the Robin 35cc which I agree with Mtn. Man would be your best bet. PM me to work out the details if you are interested.

    Robins are proven -- rock mountain hard

    those Robins are proven -- rock mountain hard

    a lot of fun -- not to brake down and -- ride that thing

    lowest gearing

    mountainman, mabman, I thought that the smaller roller would be the lowest possible gearing thus getting up the steepest hills easiest?
    The only motors so far I've been able to find in the UK are the honda 25cc and 35cc. I wanted a four stroke because I've always found their noise to be more acceptable on the ear.
    I can't really import a motor from the US - its going to cost me enough in tax just to get the friction kit through customs.

    The Honda 35 will be a good enough substitute. Skip over the 25cc one altogether.

    Build that thing.

    that is correct. smaller roller = more power for hills.

    just for's my findings, on the staton-inc friction drive kit, being used in the rain or wet streets.
