5 Stars
Silent, smooth, 31mph fast!, high quality, waterproof quick connects, integrated controller, A+
FIRST IMPRESSIONI have three ebikes and I think this is my favorite motor so far. I highly value silence and this motor and controller is completely silent while also being powerful and fast. I can not hear any noise at all coming from the motor, it's just a super smooth and silent push from zero to 31mph. Without and drivetrain noises or shifting needed, it provides an excellent super smooth, silent and fast impression.ADJUSTABLE AMPS (P14 setting)Using a 48v 14AH Samsung 35E cell battery, I get a solid 1450-1600w with full throttle from 0-31. I believe my battery BMS limits power to 30amps however the lcd P14 setting has a max of 35amps so it's possible a higher amp battery could result in even more power. I tested setting P14 to 20 amps and it reduces max power to 1000w. I also tried 17 amps and got 800w. This is extremely useful if you want to maximize battery range or if you just don't have a high end battery or if you just want smoother lower power. It is also important if riding on roads so you can adjust power down to legal limits. In Oregon it is 1000w and 28mph while pedaling. If installed on a kids bike you could dial it down even further like 250w.ADJUSTABLE PAS TOP SPEEDP08 allows you to set the maximum speed in pedal assist mode in kph. Default was unrestricted at 100kph but you can set this to any amount. I set mine to 45kph which is 28mph and the legal limit in Oregon. Note that it does not limit throttle top speed.INTEGRATED CONTROLLER (in wheel)I also really like the integrated motor controller. Most bigger hub kits have a fairly large controller box and associated wiring that you have to find a place to mount. The hidden controller on this one really help clean things up.WATERPROOF QUICK CONNECTORSAnother huge help in installation is the waterproof quick connectors. This is like snap together idiot proof wiring that goes really fast. You match up the colored end and snap the connectors together. This also really cleans up the wire mess significantly. Taking the apart requires more force than I would like but installation is a breeze.FRAME HUB FITMENTThis did take some effort and light filing work to fit my 135mm x 9mm drop out. I think hub spacing is closer to 142mm after adding the washers needed to clear the freewheel and disc just right. I also had to file down the axel bolt slightly where it slid into the frame as it seemed just a hair too tight. This all took some tinkering but totally doable for anyone who is a DIY type of person.PAS SETTINGSPAS is adjustable to either 5 or 9 steps adjustable through the controller lcd. I changed to 9 steps which makes each PAS level work in roughly 5mph increments. PAS1=5mph, 2=10, 3=15, 4=20, 5=25 and 8 or 9 =28mph with my max speed P8 setting at 45kph. Initially I wished the settings were power increments rather than speed settings but I've grown to like it ok. It is kind if like multiple cruise speed settings. My only dislike is the power applied can feel a little too much when in high PAS levels coming from a stop. If in setting 5 it is full power until you get close to 25mph then it tapers down. I wish you could adjust the power ramp up to something a bit more gradual. My radcity bikes use power level instead of speed and a bit smoother ramping. I found that limiting amps in P14 to 20 or 1000w helps snooth this out a fair bit.NO LIGHT WIRESOne thing missing is a light output connection. I'll have to see if I can modify one in, currnetly using battery powered lights.FREEWHEEL AND GEARINGFreewheel seems of good quality but is only a 14T in the smallest tooth. I switched to a DNP 11-34 freewheel and 53T front sprocket so I now have plenty of gearing to pedal at full speed. Initially I had a 44t front and the 14t rear freewheel I could not pedal faster than 25mph and it was only relaxing to pedal to 20mph. I would recommend replacing the freewheel with a DNP 11-34 and using a 52T front sprocket if you want to keep up with this speedy motor.WEIGHT and APPLICATIONThis motor is ideally suited for pavement duty. It is heavy happiest going high speeds commuting on pavement. Direct drive motors have no gears or reduction so they don't have low speed torque for doing moutain biking offroad stuff. I have this motor on a full suspension mtb and do take it offroad but a lot if unsprung weight making the rear skip over rocks a bit. A mid drive motor is better for offroad purposes. However I think for commuting on pavement this motor is perfect. It's helpful not having to shift and the silent smooth power works great for a commuter. The PAS system is not the most advanced but I think it could be upgrade by adding a torque sensor crank and cycle analyst. I may do that later. I think this motor and weight is perfect for commuting but not the best choice for offroad.OVERALLBottom line I think this kit is an amazing commuter kit in most ways. I finally have my class 3 fast and silent 31mph ebike and still a bit shocked at the high quality you get for the price. It took a little fitment work but honestly a more fun commuter rude than many very expensive ebikes I've ridden. There is a huge grin factor gain between 20mph you get from most ebikes and class 3 28mph. This ebike kit makes me want to ride more, it's really a great kit!
