This is so freaking annoying the largest file you can upload is 512 megabytes and the smallest picture I have is 3.5gig so I'm not sure when the computer software was written for this website possibly 1981? Because I don't know of any modern day picture that's only 512 megabytes smh..... Looks like...

Jumping a bike is foolishness, but with that out of the way, if you can jump a pedal bike without wrecking it, this one should be about the same.

Those nipps are for 13ga spokes. They're of no use to you. 13-14ga spokes use regular 14ga nipples. Whatever portion of the 13-14ga spoke is 13ga diminishes its elasticity, versus a straight 14ga spoke. If you're going to spend the extra for butted spokes, you'd be better off with 14-15ga double but...

Also the reason they never made it in sports is because the racing organizations banned them ( and any other major aerodynamic aid ) because recumbents and superman bikes are too fast :lol: But... 'bents win all the major cycling events! Of the many major cycle manufacturers, the most reputable one...

Semi recumbent/CLWB is the master race of all bikes.

Clearly. That's why it has prevailed in the consumer marketplace and in cycle racing for such as long time. The wide adoption of CLWB bikes by military forces surely didn't hurt.

I choose low maintenance for my own bikes, meaning direct drive hub motors without regen. So I sacrifice a little efficiency on both counts, in favor of reliability. How do you figure regen to negatively affect reliability of a system? Reversing reaction torque at the axle tends to loosen threaded ...

Andra 40 is only 25mm inside/31mm outside, which is fine for 35-40mm tires. These days the trend is to use a wide rim to maintain tire stability at lower air pressures. Are you of this. I looked at many french website and all say that 25mm rims needs at least 42mm tire. That's not consistent with c...

Hey people here’s a banana for scale.

That gives me a good sense of how big the socks are.

the fear of slamming on the rear brake and having the wheel come off the back is real. so you think just a screw (m5?) going through a slot in the torque arm and into a threaded hole in the dropout is adequate? seems what youre saying just want to confirm. That possibility is no different for an e-...

It would probably work fine without the pin, as long as it's most/all of the way into the dropout slot. The pin will prevent you from adjusting chain tension. If you want a second torque transmitting feature, make it a slot, with a threaded hole in the dropout for a screw.

thank you for the advise on spokes my max tire width is 40 so i can't go for more than 23mm internal width of rim. So andra 321 could be the option Andra 35 is a little heavier and stronger, if that matters to you. Also, Andra 40 is only 25mm inside/31mm outside, which is fine for 35-40mm tires. Th...

The Ryde Andra 40 is a good strong rim. Don't use thick spokes like the ones in the photo; they're probably why your rim cracked. Use regular 2.0mm (14ga) spokes, with washers under the heads if necessary to prevent pull-through.

No. Single speed with a mid drive motor gives you all of the drawbacks of a mid drive, without the main advantages. The single advantage I can think of is weight distribution versus a rear hub motor, but that's not a big factor. If reliability matters to you, stay well away from TSDZ2. For a winter ...

Headshok frame bores are the same diameter as One Point Five. For a tapered fork, you use an external One Point Five headset cup on the bottom, and a 1.5" to 1-1/8" reducer cup on top.

would a lower turn motor be able to handle more current (battery and phase) before overheating? No, the amount of copper and iron and the motor thermal shedding design dictate that. Low turn counts have lower resistance, thus less heat at any given current. But they also make less torque at any giv...

Hub motor Kv is meant to match wheel size. There are no other reasons, but it does seem hard to understand for many. It's also for limiting top speed to less than the available power would otherwise achieve. This can be key for staying legal/under the radar/courteous, depending on where you ride. I...

If I bought a motor that costs that much at least I would expect that it can provide a speed signal while coasting without such awkward stopgap solutions. Why? That's not an intrinsic function of a motor with a one-way clutch. This is a non-problem, but pedal cyclists figured it out generations ago...

I have messed up a couple of cars with trunk racks. I wouldn't bother with them again.

Best remedy is to ditch the car. They suck and they make those who use them suck.

Not sure what you mean by "personally," but there are definitely routes where it is possible to recover significant amounts of energy from regen... There are more situations where regen isn't worth the energy lost by not having freewheeling. Most people live in areas that became populated...

3D printing is the hot glue gun of early 21st century males. Like late 20th century females with their hot glue guns, once they grasp the basics of the technology, they stop thinking about whether it's appropriate to the job at hand. They use it in whatever situation, regardless. In both cases, thes...

The three thickest wires into the motor, and out of the controller, are for powering the motor stator phases. They're usually blue, yellow, and green. There are usually five small wires in addition to these: +5V for the Hall sensors, GND, and the three signal wires for the phase Hall sensor signals....

Day 6 Dream 8 won't help with ride quality, unless that's about picking up a hot new octagenarian ride with your sweet geriatric bike. A ride position like that prevents you from standing up on the pedals when things get rough. And standing up is the best strategy when things get rough. I find my ow...

Maybe if you had a particularly thin inner tire RTV-ed to something like a schwalbe marathon plus.. one would have just enough rubber to avoid the maximum length i've seen a goathead - 11mm. I'd go for talcum powder over RTV. If you're just looking for some extra thickness, wrapping a sliced-open t...

I'm back to correct more bad data, and be a little more confused than before. To review: That motor-wheel combo [6T 1500W Leaf, 29" wheel] has a free speed close to 40 mph, top speed of about 28 without help at the pedals. Achieving only 70% of no load speed is a sure indication that the motor ...

..i've ran 'stop flats', but they actually wore into my tube and caused a flat themselves, rendering them less than useless. But the rhinodillos have soft tips that supposedly prevent this from happening. All the different strips have edges, and the edges will cause punctures if the ends don't do i...
