Field Test: 2021 Specialized Stumpjumper - The Do It All 'Er
@danielstutt: Two thoughts... 1. Spesh complete builds are a rip off. Buy the frame only (comparable to all other frame prices), and buy these same components for closer to $7k. 2. The only reason to think of it as a $5k, $7k, or $10k bike is if you keep for 10 years. Sell your bike and get a new one every 1-2 years, and it only costs you $1000. Kinda like a lease, you'll always have the latest and greatest bike for $1000 per year ($80 per month). When you're on your last bike... keep the proceeds from the final bike sale.

Field Test: 2021 Actofive P-Train - Not Your Typical Trail Bike
@lenniDK: It’s too soon for that nostalgia trip. Steel had its run... and it was long. Aluminum had its run... still hanging on though. Titanium is too expensive. Carbon is still in its infancy. There no justifiable reason to choose steel for a bike frame at this point in time... unless its going to cost less than Aluminum. Even Carbon will be replaced with another “better” material for the application.

Field Test: 2021 Actofive P-Train - Not Your Typical Trail Bike
Yeah... I’m having some mixed feelings on this. 1. It’s not the bike for this review... I know Mike said they like to throw an oddball in there, but so many other bikes would be better fits in this field... and are on buyers radars. Have a separate oddball bike field test. 2. Mike tried to do it a solid and put some light weight parts on it... it’s probably a 36lb bike for most people. 3. It’s kinda trying to have a “what’s old is new again” vibe... but there is really no reason to choose steel these days... it’s heavy, it rusts, and apparently it’s not cheaper. Still appreciate the effort and the review by itself.

The 'Super Wheel' Claims to Offer Power Assistance Without a Motor... And We're Very Skeptical
@iamamodel: Fellas... if everyone just accepted limitations there would be no invention. Yes... welcome all of you to your recently acquired Physics and Engineering knowledge. Now that you have read it all, there is no need to attempt anything new. I too am a Mechanical Engineer... of course I’m aware of these “laws” and concepts... I was just taken back by all the negativity and poopooing on this guys attempt at something different. Yes, it may fail the fight against the laws of physics, but many inventions lead to tangential discoveries and applications.

@JoshieK: The suspension compression before a jump is for a boost...consider it an “assist”... maybe a “30% assist”... who knows exactly. I know there is an appreciable difference in loading the suspension and not loading prior to any takeoff. FYI... also works when you wanna “pump” through some rollers. Compressing down... propels you forward... who’d a thunk? Oh yeah... BMX and skateboards have human suspension... they still compress before a takeoff.

@R-M-R: Alright... then next time you approach the lip of a jump... don’t bother compressing your suspension before jumping. I’m sure you will clear the gap without that minuscule energy source.

@R-M-R: Easy... you are speaking so definitively. Can’t you concede, that this MAY have some merit... and warrants further investigation? Not only to DEBUNK, but to expand on and drive other possible uses? The springs are loaded with energy from your body weight (gravity is constant)... this “weight” is working against you anytime you are moving your body on a bike or otherwise. Using your pedal energy to initiate a roll, springs release stored energy (that gravity and your mass put into it), and springs continue to store energy with each compression (as the bike continues to roll). Store, release, repeat. Essentially, the springs that are releasing stored gravity/mass energy are the assistance. You can see from the demo that the bike accelerates from a stop with very little pedal effort.

Field Test: 2021 Ibis Mojo 4 - The Trail Rider's Trail Bike
I don’t think we should be comparing bikes with slim shocks and 34mm forks to bikes with piggybacks and 36s.

I think I’m with you here... the geo, the travel, the slim shock/fork, the wheel size... are all misaligned. This bike doesn’t fit cleanly into any category. And I think the review sums it up... it doesn’t do anything well.

@lkubica: Gravity and your mass provide the potential energy.
