Will this be powerful enough?

    I have a 26cc Homelite weedeater engine (Homelite UT-21967) and I was thinking of mounting it to a trike with a chain-drive to power both rear wheels. I was thinking of gearing it so its top speed was between 20-25mph. Will that give me enough torque to move me around at those speeds and on very small hills unassisted? I'm over 200lbs.

    26cc won't even have the power to pull the skin off a rice pudding on a downhill slope.

    Even if geared correctly? What if i gear it down to have a top speed of just over 15mph?

    I was also looking at the 99cc 2.5-3hp harbor freight engine for really cheap. I know everybody always says you get what you pay for, but they get good reviews.

    Forget about a 26 cc for a trike.
    The 99 cc HF would be a great choice for a trike and reliable to boot.

    You will need to gear a 26cc engine down to 3mph to have any chance.
    Might as well walk, because it will be a faster method of going places.

    Will 99cc engine bikes run in Sikkim or in hilly areas...

    If you can still find a 99cc engine then yes, it will take just about anything you can throw at it as long as you have gears.

    I tried to buy the 99cc HF engine for my trike in 2016, will not sell in Ca. so I went with the B&S 127cc, 3.5 HP and 5.5 Ft-Lbs. of Torque.
