Hi Bob, If I were you, I'd Hi Bob, If I were you, I'd buy a couple of those Cruzbike conversion kits now for the junior Cruzbikers. They'll be ready before you realize it. :D Charles

Hi Vovolc, I agree the longer Hi Vovolc, I agree the longer chainstay looks good with you on it. :D (And that aerodynamics are likely to be better with the bigger chainstay). The $1,000,000 question: Can you still pack your bike in the Samsonite (or equivalent) suitcase)...

Hi Vargus, I believe people Hi Vargus, I believe people have put on 36T rings on Quests. That doesn't answer your BCD question. I will point out that you can put a front derailleur and a double (or even a triple) on the Quest. It's probably over-kill, but it could be done. (There...

Hi I0, 1) Yes, I like it too. Hi I0, 1) Yes, I like it too. :D 2) Yes, it probably would improve aerodynamics. It would also make it harder to pack in a suitcase. I'd personally go with the smaller chainstay. NOTE: I'd love to hear from somebody who has the 451 with the longer...

I'm looking for a complete Cruzbike conversion kit. I'm also looking for a seat with mounting bracket. Thanks, Charles

I'm a little leary of the I'm a little leary of the "only recumbent that is hydroformed as that could change as any day. "Climbs like a bat outta hell" will be as true tomorrow as today. I'm not saying not to use the first, but prepared to change 'only' to 'first' (which is less...

Congratulations and welcome! Congratulations and welcome!

Huh. I had no idea bike radar Huh. I had no idea bike radar reviewed recumbents. Moving on... The recumbent they review is a FBB FWD. I think having a moving bottom bracket makes for more pedal steer than other bikes. That being said, I can see how chain line might affect this...

Hi Bob, In principle, this is Hi Bob, In principle, this is similar to what you get with 'Find a rider' option (which, somewhat ironically, I can no longer find on the Cruzbike page). Personally, I'd just let people go for a test ride (but then, I have cheaper bikes). So: Yes, we...

Hmm, great idea "?Get I don't know how true that is. The Sofrider and Quest were reviewed by Bryan and Larry at BROL. The reviews were fairly positive and I don't think it resolved many issues for people. Second, there are many riders of Cruzbikes who are seasoned recumbent...

What Charles is really trying This. Except, of course, I want a suspended fork for both 20" wheels as well as 650/700 wheels and I have a feeling John's gonna tell me I'm SOL, so while I'd love the fork, I'd rather keep it as it is instead of getting rid of it. When Cruzbike...

And just to be And just to be clear: Whatever you do, don't drop the conversion kit. Seriously, just don't do it. There will always be people who can't afford even $1200 for the Sofrider and others who just aren't sold on the MBB concept (it 'tis a little weird). So, in summary...

And John, it's not a 20% And John, it's not a 20% improvement in power. It's a 25% improvement in power. :D

Hi Sam, The angular momentum Hi Sam, The angular momentum of the wheels I w (where w is omega angular speed and I is moment of inertia) will be different for the two sized wheels. The kinetic energy stored in the wheels, it turn out, doesn't depend on the radius of the wheel at all...

Well. Yes. And no. And, mostly, it doesn't matter * I'm assuming your comparing the Quest 451 to the Quest 559. What matters is that the 451 wheel weighs less than the 559 wheel. As far as answering the original question, the answer is yes. (Again, you can get CF 700c wheels...

Hi Kungfuguy, Just to Hi Kungfuguy, Just to reiterate what Bob and the others have said, it's unfortunately really easy. It's just economy of scale. If you can crank out 10,000 units, you can get much cheaper prices than if you are making 100 (or less) at a time. If you think...

Hi, Just to be clear, I'm not Hi, Just to be clear, I'm not "guessing" here, I've done the math. Both linear and rotational kinetic energy of bicycles, riders, and wheels are very well understood phenomena and there really isn't any mystery here. This is advanced high school/university...

If you solve the question you If you solve the question you ask: How much force (or power) does it take to go a given speed , you'll find that neither the gearing*, nor the wheel size has a very large effect on the answer. At high speeds, it's all a question of aerodynamics. At low speeds...

Happy Birthday! Happy Birthday!
