Re: Small Solar Proposal

Okay, thanks DS. Even at twice the cost? If I had to rely on them, then Yes. For puttering around in an RC vehicle, the Turnegy are fine. If my safety was on the line, or if I had invested a lot of money in something like a race boat and planned on winning, and wanted reliable safe equipment, then ...

Re: Small Solar Proposal

Sounds like an awesome project, I'd love to see the progress as you get this built.

If it was me, I'd pick Sanyo or Panasonic cells over Turnagy. More power density meaning fewer cells and lower weight. Also probably higher quality.

Yes, but No. They won't replace a suspension for taking the jolt out of hitting potholes. you'll feel them more than you would with a crap-tastic pogo stick suspension. However, you won't h...

Re: eBike Drag Racing Timing?

Real portable timing lights are about $5000.
But they make them for RC cars, that can go wireless for about a football field in length, and run in the $200 range.

Re: Heavy duty wheels for 26" MTB with BBSHD

Pics would help. If the only damage to your wheel was a flat spot, then your rim was beyond heavy duty enough for the tire you were running. The failure point was the tire. Flat spots happen when when the tire fails to hold up under impact. This happens when the tire is too small, under inflated, or...

Re: Cheap suspension fork 1-1/8 threaded

Suntour forks are often worse than nothing. My last Suntour was flexible enough that you could see the fork bend back under normal braking. While it took the jolt out of a few bumps, it made the bike handle like a rattly, clunky, wet noodle. it wasn't pleasant to ride, and never felt safe. Trek 800 ...

Re: Aquatune - Convert Water to Hydrogen for $600 + $400 labor

ok. first problem, the energy needed to break the bonds between hydrogen and oxygen is exactly thew same as the energy produced when they recombine. So if every step in the system was 100.0% efficient, the amount of power needed to break the water into gas would be exactly the same as the output pow...

Re: Feedback on plan for first e-bike - Giant Roam with BBS__?

If the BBSHD is in your budget, it would be a great option. Sure, putting more torque on your chain and gears will wear it out faster, but those are parts that wear out eventually anyway. "faster" might be mean they are toast by summer, or toast in 20 years. sooner than normal, but sooner might stil...

Re: Challenge with brakes

I'll never be a fan of roller brakes, but it would work well and be relatively easy to put on that bike with a hub change. Adding the rim brakes could work, but the rim would need to be suitable for rim brakes. if it isn't, the brakes would crush or crack the rim. A harder but better alternative mig...

Re: Tandem Duel Electric Wheels

Really nice bike. 250w isn't going to be enough to help move 2 people very well. for one person, it would still be fairly under powered but usable. With 2 motors, it should work, but 2 people and just one 250w motor may over stress the motor and damage the gears. You may want to avoid standing start...

Re: opinions about this 500watt model & hill performance

unless your wife is under 100 pounds, i wouldn't expect a 500w geared hub motor to survive climbing a 16% hill. 8fun is Bafang's western name brand. Bafang make a good motor, and if you modified the controller for more power, it might actually make it up the hill. but i doubt the motor would survive...

Re: First E-bike Conversion advice

Skip those 350w motors. They aren't robust enough to survive off road. a 500w Bafang or MAC is what you need. And if cost is an issue, the direct drive hubs are still a good option. Heavy, but bullet proof with only 1 moving part. They make a great motor to get started out with. They have some advan...

Re: New DIY project (Stealth Bomber-ish clone), advice on parts - starting with wheels/tires

Looks like a good combo so far. Ive been curious how those Ranger 3.0 work out. Since you're building up the bike, you probably should go for a wider rim. for a 3" tire, I'd want a 45mm rim (39mm inside width). 32 hole for the front will be easy to find. for the rear, you're going to have a fun sear...

Re: brushless Dc motor controllers

A motor's speed is based on the voltage supplied. And the speed is basically linear. If 10 volts gives you 10mph, 20 volts will give you 20mph. 100 volts will give you 100mph.... as long as you also have enough amps to cover the wattage needed to go that speed. If you take the battery voltage you ha...

Re: planning new ebike build - several questions

looks like you've picked a good overkill motor for what you want to do. combining that with a ~52v, 40A controller will give you 2kw of power, a bit more power than a moped in a vehicle that weighs 100lbs less. It should give you all the performance you need. An 18FET controller is what I use on my ...
