Notice anything different besides the swing-arm and the obvious patent material?
like, the lack of a transmission?
Huh? From the description:
" an electric motor with a transmission assembly including a pinion sprocket or pulley and a flexible transmission member engaged with the pinion sprocket or pulley for providing a motive force to the rear wheel;"
I never knew I even had a squat ratio, much less that I wanted to adjust it! In simple, practical terms, can someone on here dumb this patent description down for me to grasp what principles are involved and what advantages can accrue to the rider?
What I mean, is the 6-speed is gone in that illustration. The drawing does show a gear reduction (sprocket isn't on the center shaft of the motor), but that doesn't mean it has the 6-speed intact.
Squat is basically how much the bike will squat when you give it throttle. This can effect handling quite drastically This is also heavily effected by where your drive sprocket is with relation to the wheel sprocket (in front of swingarm pivot, behind, above, below).
Looks like the motor is on an adjustable mechanical mount that can move, adjusting how much of an effect the drive motor has on the squat. Since the sprocket is behind the swing arm pivot, adjusting the position of the motor will adjust how far the bike will squat under load.
Look at figure 4, page 4. It alows adjustment of how the motor is mounted.
