How to install a motor from a brush cutter to a bicycle

To forever forget about the need to rotate the pedals when riding a bicycle, it must be equipped with an electric or gasoline drive. For long trips, of course, a gasoline engine is better, since when using it you do not need to make long stops of 6-10 hours to recharge. The most budget-friendly and simplest solution possible is to install a motor from a lawn mower on a bicycle. It has a standard tank, gas handle, and clutch, which greatly simplifies the conversion.

    For some reason, everyone.. or most of them are trying to make the drive on the rear wheel.. I.. just put an electric motor on the front... the battery is located in front.. right at the steering wheel... And then.. with this arrangement it turned out to be on the front wheel 30 % weight... rear... resp. 70%... This is when I'm sitting... naturally..
    And here they are still trying to increase weight on the backside...
