Good way to up-cycle!

Grab an empty (clean it first) soda can, small Phillips head screw driver and a AAA battery and have fun. This robot is actually pretty cool. He is cute too. We named him Pop. Get it. So cleaver aren't we.
The directions are clear; with pictures and descriptions. We helped our 5 and 7 year old. I'd recommend helping. Its also a good way to talk about the science behind robotics.  Fun little experiment for a rainy day.

I got my Rowbike about a month ago. It took me a little while to get used to the balance and steering, and now I'm commuting on it, 8 miles round trip each day. After commuting on my regular bike, I'm in good shape from the waist down, but pretty weak and flabby above. I expect that my upper body fitness will improve steadily from this twice-daily workout. So far, I'm very happy that I bought my Rowbike.

Here's an update two years later (October, 2010): The Rowbike is the best purchase I've ever made. I'm still commuting on it, and I have real upper-body strength for the first time in my life. Also, I was starting to get middle-age back pain, and that's completely gone - my back is a hell of a lot stronger than it's ever been. In the process, I've lost 25 pounds. I still have about 10 pounds to go. Once in a while, I go back to my pedal-bike when my Rowbike needs a repair - it's just too boring and too easy. The Rowbike is much more of a workout.

Is it perfect? No. It's heavy, it's slow, it's hard to go uphill, and it's not as nimble as a conventional bike in traffic. It's sturdy, but since there's only one manufacturer, the design has not really matured. It can be a pain to work on, when it's time to do stuff like replacing the chain.

I just wish I'd bought it ten years earlier.

This cycling gps works like a charm. It makes cycling much more interesting. Even if you are just a recreational rider it will help you improve your fitness level. And if you are so inclined you can compare yourself to some of the other area riders. The attachment piece to your handlebars is pure genius. It's so simple yet works perfectly. There's no big setup with this system. You just enter some basics and then go for a ride.

I switch exercises or intentencies every 30 seconds, much better than counting reps.  I bougt several to keep in various places, including one at work!

I've used this several times.  It works.  I put it on the lower chain and turn the crank backwards while the bike is mounted in a stand.  I didn't have enough room to use the top chain even with the bike flipped upside down.  Once you get the feel for the tension and line it up properly, you can crank the chain pretty easily.  I use Simple Green, and it cleans my chain nicely.  I like to run the chain through two batches of Simple Green.

It might be easier to do this with someone to hold the bike, as the tension tends to pull the bike down, making it rock a bit in the stand.

It took me just under an hour to assemble my Schwinn A10, but it was pretty easy to do, even by myself.  The instructions are clear and easy to follow.  And this device is well worth the effort.  Its a nice looking exercise bike, with a sturdy build and lots of features!  With in- handle heart-rate monitoring, a comfortable adjustable height seat, and an excellent electronic console with a broad range of presets and as much flexibility as you need, its a great addition to any home gym.

The Sigma Sport Bike Computer has been great so far. It took about ~20 minutes to install it onto my bike. It was my first time installing something like this, but it was fairly straightforward and easy.

The only problem I had was that in the beginning, I didn't know how to set up the computer itself (it kept on resetting my stats), but after I got got the hang of it, it's been great.

So far, it's been pretty useful and logs my miles so I know the mileage on my bike. Besides that, my favorite feature is probably the "trip time". It allows me to time my commute to work with both helps me plan out the day and also motivates me to beat my average time.

Can't beat the bang for buck.

We love this so far; it is exactly what I hoped for and my 3.5-year-old loves it. I was a little nervous ordering this--people told me it wasn't practical because it only has one use, and it wasn't the easiest thing to put together (all the joints seemed to need lubrication and it came with a poorly attached back fender which i STILL can't adjust/remove because the bolt seems completely frozen). But I got it together in less than an hour and it does seem built to last and safe. Just make sure to really tighten everything! I didn't get everything perfectly tight at first and I found things kind of moved around after a test ride (not dangerously, but still). Also, at first it was fairly difficult to attach the front post of the co-pilot to the receiver of the adult bike, but with a little WD-40 and some time (and practice), it has gotten much easier.

My child is exactly 3-1/2, and about 41" (which is why she can't fit in our front-mounted seat anymore). She can reach the pedals, though just barely (not well enough to pedal with me yet). Because of this I thought there was a good chance she'd dislike it at first because she wouldn't feel safe enough (and she never hesitates to speak her mind), but she loved it right away! We took a test ride around the block the first day, and a 1.5-mile ride the next. We live in a pretty flat place but we did take some small hills and it felt secure.

The co-pilot will be perfect until she can ride solo on the streets--which will probably be at least a couple more years, because we live in a city and bike a lot in the summer. In the meantime she still has a balance bike she's learning on, and I can buy a used kids' bike from someone in the neighborhood when she needs a bigger bike of her own. In short, I don't find it a superfluous buy and I'm happy with it!

I purchased this book while re-training for my first season of snowboarding since breaking my leg several months ago. I chose to focus on a cycling program when I realized that the muscles I really needed to develop were the same ones used by devoted cyclists. Therefore I purchased this book in hopes of getting an excellent fitness routine that would get me back on my board ASAP and I haven't been disappointed yet.

This program is perfect for beginners, or anyone who is just trying to get an idea of how to start a good program that can be maintained and adjusted to your fitness level. The book is full of anecdotes on Lance and Chris, much of which are unnecessary, but they make for easy reading. The book reads like a motivational biography with important fitness and cycling details spaced throughout. It's easy to read, but I would stress that this is certainly geared more towards a beginning cyclist who is just looking for an easy-to-follow program. In the process, you learn a lot about Lance, and you may even get to the point where you can identify with him and feel motivated by his experiences.

I highly recommend this book for any beginning cyclist or individual interested in both anaerobic and aerobic endurance training.

Great exercise DVD. The 20 minute no-nonsense approach is refreshing, and the exercises are challenging but not impossible. I did the 30-day program and was able to drop a couple of sizes and reverse a year-long trend of slow weight gain. For the first week, I was sure Jillian was out to kill me, but as it turns out, I didn't die -- I got stronger, faster and fitter with each day. Though I didn't get "shredded", the results are awesome and happened faster than with yoga, pilates, running, walking, cardio/strength at the gym, swimming and HIIT.

Note: it may not be a great program for you if you have problems with your knees and ankles. If you have manageable issues, just spend a few extra minutes doing dynamic stretches on your troublespots before you get into it, and focus on form throughout, even if you have to go a bit slower.

Everyone knows the best way to get fit is to use your heart. It makes sense to work out using a tool that can measure and improve fitness by "reading" this important organ. This book, which is well-written and organized, is especially good for someone who's tentative about getting on a bike or who wants to enjoy cycling while getting the maximum return for output. Simple steps, clear explanations, diagrams paired with workouts for all levels: the authors offer a flexible system for enhancing cycling workouts emphasizing health, fun and self esteem. Can you tell I liked it? Makes a great gift for reluctant couch potatoes who really want exercise but need a little help with a fresh start.

This cycle is great!  Since having a baby, I can no longer make it to the gym so I pedal all day at work averaging 14 miles a day.  the cycle makes no noise.  At 5ft 3 with a normal height desk, I have no issue with my knees hitting the underside of my desk.  The cycle seems sturdy. I wish it had some way to lock it to my desk using a bike lock.

Easy to swap out the old pedals for the new. I find them a plus to use when you have done biking in years!

Great work out video, and I love how you can progress through the levels.  The other great part about it is how quick the work out is.  I can do it while my kids eat breakfast, and I feel energized for the rest of the day.  If you get sick of the level you are on, you can go to another level and just modify the moves.  I noticed results after a couple of weeks.  If you stick with it, it will work! :)

The JetFluid Pro Trainer does exactly what it says it will do.  It lets you attach your bicycle to this stand and ride indoors.  To that extent, it performs admirably.  I have a Trek 7000 as well as a Jamis 29" mountain bike - both outfitted with Moon Saddle seats. Since discovering the Moon Saddle seats, I no longer care to use the standard health club stationary bikes during the winter months, opting instead to mount one or the other bicycle to the CycleOps.  I have it set up next to the couch in my Man Cave, and when I need to get a ride in, I put on headphones and get a good workout.  In terms of resistance, this delivers a similar ride as riding outdoors - absent the head wind of course.  Outside, I average 14mph.  The effort and distance seem to be the same with the bike attached to the CycleOps.  If you ride a regular circuit out of doors, you'll have as much headwind as tailwind, so it makes sense (to me at least) that my average miles per hour are about the same inside as out.

The base is very stable, but you will probably want a support stand (sold separately) for the front wheel.  It's also very well made and requires no tools to set up.  You can be riding 10 minutes after you open the box.

My only complaint is that it's not nearly as quiet as I had hoped.  The faster you ride, the higher the pitch and loudness.  Pushing 16 mph, I really have to crank up the volume on the stereo (even with headphones on) to be able to hear anything other than the whining coming from the Trainer.  At lower speeds, this isn't so bad.

If you can find one at a store to try out, I suggest doing so before buying, just to make sure you'll not be deterred by the sound at the level you think you might be riding at.

Good Luck.

Loved it!
My gal got this for her 3rd birthday and she easily (EASILY) transitioned to a 2 wheeled pedal bike at 4.
After teaching her older siblings how to transition from training wheels to 2 wheels, I can say there is really no comparison. (Training wheels are a nightmare, btw.)
I can't compare it to the Strider bikes, but this one worked extremely well for my long limbed lady. (And she loved her pink bike!)

I am not a hard-core cyclist by any means, but as I grow older I am getting much more aware of my mortality.  As a result, I've noticed that on many streets, the concept of a "bike lane" is a charming fiction - what actual utility does a wide stripe of paint on asphalt do when I am on my bike and someone else is in their car?  Not much.

Long story short, I'm getting much more comfortable with the idea of grinding away on my bike in my garage rather than hitting the road unless I am very confident that cars and my bike won't mix. It's also nice to use this when the drizzle season starts - the combination of falling leaves and light rain can make even the most innocent-seeming street a nightmare.

So I've taken a dive into a resistance trainer, and the Schwinn Mag Resistance trainer works well.  I had to YouTube the instructions as I am not all that familiar with bike part terms, but once I found the video of how the different gadgets worked I was up and cycling in about twenty minutes.  The trainer is extremely stable - I was worried that I was going to be flopping from side to side, but this is extremely stable.  Adjustments to resistance are reasonably smooth and calibrated - it's on the magnetic resistance system rather than a physical clamp on the wheel, and it seems to work well.

No trainer will eliminate the tedium of riding a stationary bike, but this one does what it needs to do.
