How does the riding experience compare?
i am glad you asked my friend
handling. compared with all my other bikes, this one handles the most like a regular bike. steering is noticeably quicker without the gyro effect from the two spinning motor masses. although, at higher speeds the 2wd feels safer. this bike is approx 5kg lighter. the c.o.g. just about makes it invisible. i can almost bunny hop this thing. endos and wheelies almost like my old 82' chromoly red-line bmx
RL Osborne is the man!
acceleration. not as fast as dogati or duty cycle 2wd but still feels like a slingshot in the first couple of gears. with the addition of the dual chain guides, shifting is very reliable and bang on each time. i let off the throttle just long enough for the forward momentum of the drive-train to spin the chain into gear (my twist shifter and throttle are on the same hand). the internal 3-spd shifts fine this way as well (though i don't wanna push this hub).
top speed. not sure yet cuz i'm still configuring this new FOC controller /w field weakening. using the old 12-FET infineon on an 8T stator, top speed was around 7kph slower than the 2wd. haven't top speed tested the 12T stator yet.
hill climbing. makes it up the super steep slope near my house but works harder and climbs slower than my 2wd bike with the same battery. i've really gotten spoiled riding the 2wd.
pedalling. easiest to pedal cuz it's lighter. however, the motor:pedal cadence is still a little high even with the 12T. if i wanna assist with my legs, it won't be in the most efficient gear for the motor. with the hub motors it doesn't matter.
stealth. duty cycle hardly got any "i know that's an ebike look". but then peeps here are pretty clueless. after this bike is done, i don't think it will draw any attention at all. with the open side cover, driving this thing in 6-step is loud enough to disturb my "connecting with nature" experience. in FOC it is nearly dead silent--quieter than my 2wd in 6-step. my crank freewheel is silent as well. gotta hand it to Mac for the very noiseless clutch.
looks. dogati, hands down.
fun. as with driving stick, it's fun to hammer out the gears..sometimes.
if i had to choose between dual hub motor and mid-drive, now i'd have to say 2wd. the duty cycle with 200A pack and dual FOC controllers would still be my preferred urban utility, mountain exploration and cross-country vehicle--gives me peace of mind and just works. the dogati would be for the weekend, night-time sprints through downtown. duty cycle mid-drive..when i'm out riding with non motorized cyclists and want to remain incognito.
and that is the "trews" my friend
