Re: Newbie E-trike Build

I haven't had any regrets with the aluminum frame. The only issue I had is the slighter softness of the rear dropouts, so I used 2 opposed torque arms, on each side, to really immobilize the hub motor axle from turning in either direction. It hasn't budged so far over the 19000 miles. The mesh seat ...

Re: Newbie E-trike Build

Performer brand...these are excellent value trikes you might consider - particularly the JC70 model...customer service is very good shipping directly from Taiwan. A small amount of assembly is needed out of the box. Probably the next step up the trike food chain in terms of quality from a KMX but ch...

Re: Charge a battery with another one

Endless-sphere members seem to have a strong disinclination to diode based pack isolation, but I have this on both of my double pack bikes - one a Schottkey from when ebikes.ca used to sell them, and one ideal diode from Sphere member "Tiberius" in England. I never have to think no matter what the s...

Re: Downtube 9FS folding bike review - my take

Try the Cannondale Hooligan 8, if you can find one. Love mine...way better than the Dahon Speed 21 I had in the old days, which your review reminded me of. Very good review. I also had my eye on the Swift, back in the day when they were readily available. These small bikes are too fun to ruin with f...

Does 5 minute charging mean I need to pull 40 amps out of the wall plug at MacDonalds?

Re: Xiongda YTW-06 mini hub motor

I am also intrigued with this motor, having run several Cute100s. I did burn out one Cute100 at 20 amps/48 volts - restricted to 15amp controllers, they are very nice to ride. If this smaller version can do 12 amps continuous at 48 volts, with good torque and good freewheeling, we may have a winner....

Re: Charging parallel battery packs

Probably a good idea to keep them isolated using a Schottky or ideal diode. I use two lithium packs, both with BMS, through a Schottkey on one trike (originally from ebikes.ca), and one using an ideal diode (from Sphere member Tiberius in England)..Nary a problem in 18000 miles and no need to worry ...

Re: Smart Pie V starts up with a jerk

Pedal first means there are no Hall sensors needed to start the motor, but it must be moving a little bit to operate. Pedal first equals sensorless controller. If it was sensored, you wouldn't need to pedal first - the motor could start smoothly from zero.

Re: Smart Pie V starts up with a jerk

Isn't this just that you have a pedal first controller? That seems to be able to start the motor without any motion at all (jerkily). That fits the pattern of my 9 continent pedal first setup. It will only start smoothly if the wheel is moving forward very slightly. If not, could be jerky forward or...

Re: Trident Spike Trike build + Magic Pie 5 Vector + Solar panel

Sweet! Good place for the batteries under the seat. And I think you will enjoy the troublefree performance of the rear hub motor. It is similar to my trike build with the heavyish 9Continent rear hub on it. Which as given me no issues for 19,000 happy miles..

I've got 19000 happy miles on a great rear hub motor (9 Continent) on my Actionbent/Performer trike that I put together in 2012. Slapped on a 7 speed freewheel onto it. I think thos...

Re: My Experience Converting an ICE Trike to a DD Hub Pedalec

I hate to say it but I think your torque arms are reversed...they are pulling the wheel in the same direction as the reaction torque (opposite to the direction of the wheel). They should pull in the same direction as the main direction of travel of the wheel, opposing the "equal and opposite" reacti...

Re: Back Wheel Motor vs Front

I'm a small bike guy, preferring small geared hub motors like Cute100 and MXUS, after building many heavier ebikes with 9C and Crystalyte. I like the motor on the front, as the battery on the back with the motor on the front gives better weight distribution on the bike. And I like the 2wheel drive. ...

Re: Chinese Battery....hmmmm, with Pictures!

Did you check the relay on the on-off switch. I had one of those burn out on a pack like this...they are lower spec than they should be. I ended up wiring around it to get the pack to work.

Doesn't it make sense to integrate your starter battery, house battery, alternator and solar panel? Every time you are on the road your house battery would be charging, as well as your starter battery, off the same alternator in your car...

Re: Quiet motor advice for low top speed but high torque

Personally, I found the Q128 motor to be pretty lame at 48V with a regular non-sinewave controller. Is there a big difference between the normal Q128 vs the Q128C or Q128H versions?
With the "normal" non-C non-H version, the Cute 100 was way better, and smaller. What am I missing?

Re: Snapping spkes

Recommend brass spoke washers at the "shoulder" of the spokes where they emerge from the spoke holes in the hub washers. That is usually where they break, in my experience. And buy good double butted spokes like Sapim, or even rebuild with 12 gauge spokes.
