HI All,
Just thinking about all the challenges of making a multi speed transmission for the happy time when it dawned on me that maybe the hybrid approach may be the best of both worlds and maybe the best overall situation (well until the multi speed tranny becomes a reality at least....then we could have a true multi speed hybrid...anyways that's for later)....
OK.... so here goes, start off with a basic happy time motorized bike.... then add a full electric set up to it (front hub motor so that the rear hub may eventually be swapped out to a Nu Vinci to allow multi speed for the happy time)....
We would then gear the happy time with a 32 t or smaller rear sprocket (assume a 26" wheel).....we would gear it high (engine wise) because we would rig the throttle so that the electric hub motor would get the bike moving initially(motors make the most torque starting a zero rpm so rapid acceleration from a standstill would be possible)and then switch off for cruise and top end....A " boost" switch may be added to allow the hub motor to help the high geared happy time up the steepest of hills...NOTE: may be able to use a left hand throttle to control the electric motor for 2 wheel drive!( let's go snow riding!)...just have to manually synchronize engine and motor speeds.
So now we have rapid off the line acceleration (electric motor) ,
then for cruise and high end we use the Happy time (since it is now geared intentionally high we have a rapid cruise at moderate RPM's AND and insane
top end).
If we encounter steep hills and the happy time needs help....no problem...Electric motor to offer assistance!
PLUS....we now can have the ULTIMATE lighting system!...Why?...Because at cruise, the electric hub motor can act as a generator to recharge the battery
and provide juice for all the mega powerful lights you care to run ( no more problems with small rub the tire bike generators or constantly buying or recharging batteries for the puny lights we now run)....well within reason but light years above what is available to us now...
Oh, you can also save your brakes from wearing out too, because when a motor generates electricity it provides braking....wow a jake brake for a bike?!?
Also, in case you encounter or want to be stealthy you could just use the
electric until the juice ran out then you could Happy time it home....electric may be good around police too if you are paranoid.
So what do you think? The best of everything....well except for a little more weight and cost?
