Re: Ford etruck F-150 Lighting - Opinions?-

I think the groundbreaking electric truck deserves a lot more attention here. What i'm really curious is, what do you think is more likely to lead to a mass electrification of trucks.. The Cybertruck or the F150? Here's Ford's take: -nci3x5lW2c I think that since this is America's most popular vehic...

Re: E-bike mid-drive motors hardly outperforms hub motors

It's a fallacy to think 10spd chains are weaker. If you actually look at their ratings the 10 and 11spd are stronger than the older designs. The only difference is the plate thickness and that isn't where chains wear, it's in the rollers. Chain line and staying in the larger cogs is how you save dr...

Re: Cycle Analyst - still solid choice?

I love my cycle analyst v2's and never really liked the idea of the v3 and had some negative experiences with them inducing latency into the throttle response.. which bugged the **** out of me. I think an update to the aesthetics of both is warranted... an oled screen with a smaller outer border wou...

Re: New geared hub motor trend: go big!

Would certainly like to see how these motors stack up to the MAC.... which is still one of my favorite motors.
The weight is off the charts. knowing what the real continuous power level is would be helpful. Where's the dyno graphs, bafang? :)

Chalo, If nothing else, getting a electric vehicle in the hands of some of our redneck brothers so they can experience an alternate mode of transportation will be beneficial to our planet's wellbeing in the long run.

100% of my furniture breaks down to fit inside a small car. Including my bed frame.
It was all purchased specifically as such.
I once had to haul a couch in a little suzuki wagon with a 1.6 liter engine.
other than that, no need for a large vehicle here.

Re: Ford etruck F-150 Lighting - Opinions?-

I recently moved and had 10 loads of stuff to take in my little Yaris, 10 miles away. My car averages 50.6mpg but the extra trips back and forth required a use of more fuel and a LOT more of my personal time than if i were to say, rent a u-haul. So my little vehicle is at a huge logistics and effici...

Re: What the heck is wrong with UPP packs!?

I've been watching Louis' videos for quite a while. He's not the sort to make accusations without a good case. And very intellectually honest otherwise.

There's surely footage of him riding his bike with a UPP pack on it in numerous videos if you want more evidence that this is a UPP battery.

Re: What the heck is wrong with UPP packs!?

I love how their response is basically 'look, we're a real company! and we have certifications' instead of mentioning any design features that make the battery safer.

The video is more of a dodge than anything else and makes me respect a vendor even less.

Re: Ford etruck F-150 Lighting - Opinions?-

I think it's pretty good by Ford standards but the Tesla Cybertruck will whoop it due to better range through aerodynamic and drivetrain optimization. The Ford truck could have had a 50 mile longer range if they bothered to stray from the 'make it look like a brick' chassis design and probably compe...

Re: I Am Buying A Kit For My Trike

A bike that does 15-20mph won't need much of a battery or much of a motor. I'd consider at the largest, using a 500w geared motor on 36v or so. I have a few hills, and one long steep one. My Sun Trike is hard to pedal. I can't stand up and pedal! It is ALL with my legs. Very little body weight. I d...

Re: Maxarya Ray 2 Semi Recumbent w/high efficiency mid drive

Just some news.. The wider bottom bracket didn't work out. Still have way too much metal to shave off the pedals. I need a 130mm wide bottom bracket at a minimum for clearance. Not happy with that. Such wideness will probably piss off my legs. I could buy some 175mm pedals and re-thread them for abo...

Re: New Mahle Motor ?

Peak efficiency of a BLDC motor is 98.4% ( CSIRO axial flux motor, circa 2010 ).
Efficiency curves on motors like these might be broader despite a lower peak due to the variability of the second field, which is good, but not as earth shatteringly good as the press release would indicate :bolt:
