Re: Direct Drive Gearless Hub Motor Drag Technical Q

The small DD in a 16 inch wheel is probably the best motor choice you could imagine. Get a programmable controller that doesn't have stupid limits or weird hitting the brakes type behavior when you hit 20.00001mph. Ainnobodygottimefodat 8) 25mph on a 16 inch wheeled bicycle with no suspension is pro...

It's happening alot now, my late 2017 1000w conhismotor hub surprisingly came in 30mm and 0.35mm lams
That's impressive for a brand not normally associated with anything exceptional. Maybe the manufacturers are phasing out those old chunky 0.5mm lams.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

There's a lot of clones out there. A lot of these companies are kind of slapping together common parts and calling it 'their motor'. This kinda design has been around for well over a decade. The ebikeling motor doesn't look too bad, maybe the windings are a tiny bit sloppier. You may be within a hai...

Re: High performance & durability Cannondale Semi Recumbent

Interesting, How much resistance will be in the 16 awg wires that are left in the motor ? Won't they heat up for the amps you will be pulling through them ? The remaining 10% of the 16 gauge wire will create some heat, but it'll get soaked up by the other 90% of the wire that's 12 gauge, and not ge...

Re: High performance & durability Cannondale Semi Recumbent

No front motors here. Absolutely not! When i say 16" wheel, i meant 16" in motorcycle size. Aka the rear. It would be cool to utilize the smaller front wheel for an even crazier power density, but there are just too many problems with the front end of the bike. Anyway, i had the spoking on the leafb...

What guage wire are the Phase Wires ? Too small! 16 gauge, according to my wire strippers.

Re: Affected by Tariffs?

^-- 100% on the mark.

I've been buying ebike parts lately and noticed they are all trans-shipped from hong kong. The shipping has increased in price, but i'm not seeing an increase of the prices of the product.

I wonder how effective these tariffs are.

Re: Lower back pain and bikes

When I had my beach front apartment, I used to get on the bike path early in the morning and ride my road bike at least 150 miles per week. Sometimes more, like 85 in a day. In that position your neck really takes a beating not to mention your prostate and tail bone. I have a road bike currently ( ...

Re: Lower back pain and bikes

Most people remark that semi/full recumbents are the answer for the back. Of course, your mileage may vary. My back loves it, but since strengthening my core, i can do upright, forward, recumbent, whatever.. but recumbent feels the best. Since we are not quadrupeds, it is less natural to be in this ...

Re: Direct Drive Gearless Hub Motor Drag Technical Q

DDs will always have drag. if you want a light, occasional assist motor, and not having regen is okay.. you will want a geared motor. Geared motors are also much lighter when you're in the <1000W range anyway. If you see negative torque, i really wonder what your settings are on the simulator ( did ...

Re: High performance & durability Cannondale Semi Recumbent

+1 to tailbox, especially above 25MPH. Although it seems illogical, a simple front fairing won't give you much if any speed gains. I wasn't aware that the rear was that important! Anyway, the leaf motor is in. I've never seen a Chinese company do this good of a packing job, so hats off for that. Ho...

Why a 29er? older bikes with 26" wheels tend to have short travels like you desire. They also more typically have the right sized/shaped dropouts for using a hub motor with.

There's an interesting trend of a lot of popular youtube vegans going full carnivore. And there is a huge backlash going on amongst the 'true scotsman' vegans versus the 'fake ones'. Interesting development.

Re: High performance & durability Cannondale Semi Recumbent

If you don't specify a speed, they'll give you a 4T motor by default.
The shipping did go up, but god damn if that isn't a lot of motor for the dollar.
