Re: Hub motor industry dying?

Technology moves at a fast pace.

Hubmotors are where DVD'S were for video about 6 or 7 years ago. 6 or 7 years from now there will still be Hubmotors on the market but they won't be the majority.

Re: GMAC vs MAC and Infineon vs Phaserunner

3000 miles on a MAC 10T and Phaserunner at 52V 30A. Another 1000 miles before the Phaserunner with Infineon at 52V 40A.

That's on 65 lb trike with 180 lb rider on mountain roads. No trouble or noises or backlash. Solid.

Re: GMAC vs MAC and Infineon vs Phaserunner

Been riding a trike with MAC10T, Phaserunner & Thun a few years now. Quiet, efficient, powerful, with ideal response.

Really appreciate the clutch.

I've bought and tested over a dozen systems and played with configurations, this one is by far my favorite.

Re: Fat Tire Folding Ebikes

Bought a Sonders fat folder used last week. Also have a pair of Scorpion trikes with MAC 10 T motors.

Sonders makes a great product two thumbs up. Rode it over the London Bridge and put about 20 miles on it last weekend in Lake Havasu both on and off road. Excellent all purpose machine.

Re: Need Alternative to Sram Dual Drive 3

HPV Scorpions were equipped with DD3's you may want to watch Bentrider classifieds. I have a pair of them, but not willing to part with them. Here's the latest, hub only, and I suspect George snapped it up, but can't say. Search BR classifieds for SRAM. http://www.bentrideronline.com/messageboard/sh...

Welcome to ES. Looking forward to your pics.

Ebikes handle so much better when the weight distribution is right.
That's especially true on trikes as well.

MAC 10T for a 20".
Field Oriented Controller like a Phaserunner will tone it down to near silence.

Not many ebikers are willing to pay the cost of this chemistry yet. They've still got about 15 years of R&D to amortize.

Re: Arizona Electric Bicycle Law changes (2017)

The only real way to lower the trike weight would be a complete rebuild from scratch. Piece by piece wouldn't be worth the effort. Not even close to cost effective to design and build a one-off e-trike, and the market isn't there for volume production just yet. Off & on between design contracts I'v...

Expect the escoot and ebike rental companies to raise visibility to get more ebike regs. Dallas just banned ALL MOTORIZED vehicles from parks and trails.

Re: Tilting trike pivot location

When the pivot point is above the Center of Mass (COM) the rider leans into a turn, but does that by swinging their body mass to the outside of the turn, more tippy that way. Conversely moving the pivot point below the COM as a rider leans into the turn, they shift more body mass to the inside. Howe...

Re: What gauge are the throttle wires?

FWIW.

USB cable with JST & heatshrink works very well.

If you want the best cable, look for Mil-Std M27500 grade, 22AWG, but its not cheap.

Depending on how the tariff is structured and enforced, it could be a benefit even for standard motors and kits sold by Grin.
Country of Origin is what it will be based on.

Re: 12T MAC motor and high current

I ran a 12T for about 1000 miles at 40A, followed by about 1200 miles @ 30A, and another 500 miles @ 15A. No problems so far. At 40A it will utter some potentially self destructive sounds with an zero ramp controller that snapped to full throttle from a stop. At 40 amps (52V) it would push my 270 lb...

Re: Using a hub motor as a mid drive?

That's something I've been entertaining a while myself for a stealth e-trike. With an array of torque sensing BB's, motors & FOC drivers out there it makes sense to try on a recumbent. Trikes offer some unique challenges to optimize configuration. Keeping the added drive/battery mass low with proper...

Re: A few questions about e-bike motors

Motors (boosters) work best when they switch poles while powered. Full power at 0 RPM = 0 efficiency. Efficiency isn't linear to speed, more like logarithmic to speed. Depends on the motor design. No matter what booster you choose it comes with advantages and disadvantages. Efficiency, simplicity, g...
