    Cruzbike on Welsh Mountain Roads in Winter - GCN

    In between the first GCN video and this one, the bike has been borrowed by a very tall rider who needed the extra-long chainstay. I agree, the chainstay was too long for Hank. But moreover, he needed to practice a lot more on the bike before tackling such a tough route. We had no control of what...

    B2B Cruzbike tandem from two T50s

    Yesterday I put up a Youtube video with this description: We call it the "push-me-pull-you", made by friends of ours who like to make stuff. We donated two T50s and got this back on loan. It's quite fun to ride. Maria loves the clear view to the rear, looking straight into the eyes of...

    GCN and Cruzbike

    We've had a 50% increase in website traffic since the GCN video dropped. That hasn't yet translated to sales, but I'm sure the sales will eventually follow. Thanks for being a great ambassador for Cruzbike!

    Short crank questions answered here

    Cruzbike recently ordered a quantity of high quality short cranks made by Croder Cycling in Taiwan. These are now listed for sale on our website. We have been looking for high quality lightweight 145mm cranks for many years, and then came across these cranks at the big bicycle show in Taipei...

    Cd*A testing in preparation for the WTTC in November

    The stock seat is a bit more aero than the CF adjustable seat. Anything that sits you up higher into clean air is going to increase drag. It may be worth it if you are more comfortable. In other words, the ergonomic gain may be worth the aerodynamic cost.

    Cd*A testing in preparation for the WTTC in November

    Thanks, Larry. I already have too many subscription services, so I will stick with my spreadsheet. It's free and I know how to use it. I might take you up on the offer to spend some aero-testing time at Technology Circle. Now, for the latest testing results: Maria and I did a simultaneous 8...

    Grin Motor on an S40

    I like that battery placement. It's ideal. So Grin makes a hub motor that is thru-axle compatible. That's great to know. That looks like a super fun bike!

    Cd*A testing in preparation for the WTTC in November

    Maria and I went out for a 40 mile training ride this morning, including four out-and-back laps on the "Tropical Trail" which is a beautiful road that is only a few meters from the Indian River on the Space Coast of Florida. Maria started out with a stock rear wheel, and I started out with a...

    Another V20/V20c rear rack option: the S40 rear rack

    Hi Flakkjacket, This pannier fits the S40 rack perfectly. It just hit our warehouse. If you don't see it on our accessory page, directly search for "Everyday pannoer" on our website. -Jim

    Affordable "Cruzbike" Short Cranks

    Looks like they are made by Zeroing in China and are nice-looking but poor quality. https://chinertown.com/index.php?topic=4120.0

    Affordable "Cruzbike" Short Cranks

    Other than the trademark violation, these might work very well! I sent inquiries to multiple Chinese companies about making short cranks several years ago. Maybe this is the result.

    Another V20/V20c rear rack option: the S40 rear rack

    The Vendetta is not just for racing. For those who find the V20/V20c their go-to bike for commuting or long leisurely trips, there is naturally an interest in carrying stuff on a rear rack with or without panniers. There is a good thread about this here. Another option is to use the S40 rear...

    new to 'bents, question, knees...

    On my V20 I am able to unweight my hips and allow them to float above the seat. Other times, I sit up and have my weight fully on my hips, and sometimes, the weight is distributed more balanced across my hips and back. I had issues with knee pain the first year or two that I started riding big...

    Tire pressure and wobble over 32mph

    When Maria first started racing and going fast in large crowds of bikes, she got wobbles at high-speed. It turned out she was scared and her hands were trembling, causing the front to shimmy. Once she realized what was happening, she learned to get a steady firm grip on the bars. I would check...

    Florida Safari

    I haven't had a chance yet to write a blog about the Bike Safari week. I wanted to put something brief up here to say what a great time I had, and to thank all the Cruzbike riders who came out and made it such a special event. We had 16 riders (5 women and 11 men) sharing the roads and sharing...
