    TTrike!!!!

    Florida HPRA TTrike racing results! I really appreciate all the great comments and suggestions. Please keep them coming. This TTRIKE prototype gave us a great way to test the concept of a drop-in tilting bike-trike converter. There is nothing like racing to put a design to the test...

    Front Disc Wheel

    Front disk wheel not for everyone My first comment is that if you are going to run with one disk wheel, make it the rear wheel (our non-drive wheel). I've mostly left my disk wheel on the rear for all rides. It's very fast and not been a problem in crosswinds. Getting a non-drive 700c disk...

    Vendetta Ready for the Heat

    On Labor Day Maria and I rode in the annual Tour de Moore, which is about 103 miles with 4400 ft of climbing in hot and humid weather. Here is the bike equipped with four water bottles minutes before the start. I was able to easily reach all of the bottles while moving fast and I was glad I...

    Cruzbike RAAM team

    I would enjoy a 4 or 8 person I would enjoy a 4 or 8 person RAAM relay and it plays to my riding strengths better than super long solo rides. It's also over pretty quickly... one week off work and you are done. Logistically, a relay is harder than solo because the train NEVER stops. More riders...

    Overall weight and sporting success on a bike

    Hi Ernest,I think I am Hi Ernest, I think I am reading that you've decided to lose the extra weight. Congratulations because that is a big decision. I weighed over 200 lbs. several years ago and I'm now down around 182 lbs. For me, diet is AT LEAST as important as the exercise. I...

    Maria's sister has passed away

    After a 20 month battle with brain cancer, she died this morning. Jenny raised five kids with her husband Ray. She gave Maria the inspiration for 3000 Miles to a Cure and her amazing victory in RAAM last year. Jim

    another electric option

    rim drive in the rain Hi Eric, Good point. Maybe this drive system need a custom made wheel with a bit of extra rim to allow a toothed interface so slippery conditions wouldn't cause the drive to slip. That wouldn't add much weight. Jim

    another electric option

    e-Cruzbike We have a Sofrider here in NC with a very heavy battery and hub motor on the rear wheel. It's very fun to ride, but not so fun to load in the car. Adding electric assist to make a FWD bike "all-wheel-drive" is very tempting. All recumbents can be tricky getting started from a stop...

    Couple blogs while crossing the USA

    Keith and Joy Kling are riding Cruzbikes on a 4265 mile tour going from Oregon to Maine this summer. They are planning to do a lot sight-seeing and cover about 60 miles/day. An interview on their local TV news station is here with some nice video footage of their Silvios and a trailer...

    "energy-sucking handlebar-on-a-stick" ???

    LASER data on handlebar flex Hi All, This past December, I did a series of laser lab experiments with our forks and handlebars. In this particular experiment, I compared the amount of torsional flex of the Sofrider vs. the Vendetta handlebar, while securing the front wheel in a trainer and...

    Initial Conclusions on the Silvio 2.x Cockpit for distance riding

    comparison photos My preferred handlebar for the Vendetta is the Gary bar from Origin-8 with 5 to 6 cm sawed off the ends and filed down smoothly. The 31.8mm clamp version of this bar has gotten very hard to find. I like it for the extra reach (I prefer arms more stretched out) and the...

    Building my new Silvio, need your bragging help

    Eletronic shifting Hi Seth, Maria and I have had the most experience with 20-speed SRAM Force and Rival groupsets, and they are light and work very well. However, the bike I am riding the most right now is a Vendetta with Shimano Ultegra Di2 electronic shifting. I love the flawless shifting...

    silvio sram force assembly pack?

    just a typo If you order the Force Groupo, you will get all Force components. That was just a typo. The exception is if our supplier is out-of-stock of a certain item, in which case we may need to make a substitution to a higher or lower level (but compatible) groupset item, but before...

    Things you shouldn't do on a Cruzbike

    I take my Golden Doodle (3/4 I take my Golden Doodle (3/4 Standard poodle and 1/4 Golden retriever) on Cruzbike walks quite frequently. He trots alongside and we have had no problems. He is good at "heeling" on the bike, and also, I hold the leash so that it is not attached to me or the bike...

    Aero wheels

    You betcha The VN loves aero wheels. Finding true non-drive disc wheels is tough. We had one made by Renn and it works well if it's not too windy. Deep rim wheels make a good compromise. If you are climbing a lot, the added weight may not be worth it. We will be bringing a selection of...

    Selling Silvio

    Hi Mick, Glad you are finally Hi Mick, Glad you are finally getting some more confidence, balance, and skill on the bike. Differenct people have different learning styles, and I think doing some specific skill-building exercises can be very helpful. 1-legged pedaling, from a start, or while...
