Mike: Yes, steep climbs on cruise setting result in surging. On the flat to mild hills, cruise works nice. Typically, I set it to 15 or 16 mph, then pedal at about 100 watts of human power that will increase the bike speed a mph or so. The WATTSUP meter will display a reduced current draw...

I bought a Mac 10t, 9 FET 3077 Infineon controller, programming cable by which I set it at 18.5 amps max and 50 phase current to smooth the start up some. For battery a 50v 14s5p, all from EM3EV. I added a WATTSUP meter to keep track of electrical flow and usage. It's mounted on a 26" x 2.25...

I've been using a Watts-Up meter on each of my bikes, both running up to 58 volts. They work well, showing total watt hours and amp hours used on a ride, as they dynamically display watts and amps being consumed. They also record peak watts, peak amps, minimum volts. The displays are very...

1boris: I am very interested in your observations and comments on the Mac 12t and how that has worked out for you. My wife's bike is a step-thru with 700c x 47mm tires. She doesn't really like to ride above 15 mph, so in adding a motor setup to her bike I have been leaning toward the Mac 10t...

Larry: I'm running a 500w Falco on a Trek 7300 with 700c x 40 drive wheel, using an AllCell HE-3620. The motor is very quiet. I weigh 160 lbs. Top speed with me pedaling is 31 mph. Pedaling effort at 25 isn't real high. For your weight and the performance you want, I'd say you want at...

Could the slightly higher drag of the Falco vs. the Bionx be the result of a 500w vs. a 350w sized motor? IE; given similar engineering, a more powerful motor would tend to have proportionately more drag?

The_dude: It would be good to install at least one torque arm one your motor. The motor shaft has a great desire to rotate. If it does so, it will damage / destroy the dropouts, and likely cause you to crash. A search of ES for the subject of torque arm will bring up a lot of stories...

Liveforphysics: I'd like to back up to your comments regarding patented designs. I understand your desire for openness and the free exchange of ideas. It does remind me, though, of a now deceased man named Larry Burkett who gave financial seminars and was very free and open with the supporting...

Most of the technical discussion on this string is way above my level of understanding. However, I do have a torque sensing 500 w Falco rear hub motor on a Trek 7300 using an AllCell HE-3620 battery. The drive tire is 700c x 40, rear sprocket is 11-32, the front sprocket is a triple with 48...

the_dude: For weight vs power, check out AllCell's site at www.allcelltech.com/products/electric-bike for specs / weights. Soon they will offer their "Summit Battery" line, which will be frame mounted. No specs yet. My 36v 20ah AllCell in a TOPEAK MTX bag is 12 lbs. Also, see...

the_dude: Check out my prior posts on the Trek 7300, Falco 500w and AllCell 36v 20ah battery. My AllCell tops out at 41.86 volts at full charge. I've done multiple 35 mile rides with plenty of battery to spare, but averaging around 18 mph. I weigh 160 lbs in clothes. Pedaling hard, my bike...

Bike_on: West central Illinois has been too cold to ride at all this winter, so I have not ridden my bike since the program update. The console is the original. The program update is supposed to cause the original console to display Amp Hours or Watt Hours as an alternative to the Voltage...

I have a late 70's Skid Lid bicycle helmet with 3 snaps and attach a motorcyclist bubble shield for cold weather riding, along with wearing a neck warmer and ski cap under the helmet. It really works well.

Hustlecat: It looks like a really small motor on their bikes. Not sure about the battery they include. You'd really want to test such a bike to see if it would meet your needs. It doesn't look very powerful... not much help on hills or headwinds, or when you want real speed. Website...

Bike_on: Using Rakesh's program, last night I updated the my Trek 7300's 500w Falco torque sensing motor and changed one value using the GUI as a check. Too cold in Illinois to test ride it. Hopefully, the update will take care of motor control and run-on issues my system has had. In...
