    Tandem recumbent + Cruzbike front end = all-wheel drive?

    Even IF this were possible - it will not make the slow and plodding feeling any better. You would have to cut off the entire front end at the head tube - rendering the bike ruined before even trying the experiment. That is also a 20" wheel fork on the stock bike, so changing that to a taller...

    S40 or Q45?

    Jeff, Definitely no belt drive. Not as long as I have a say in it. They have more resistance and are overall less efficient than a chain for the average riders wattage - and I have always said when belts start to show up on race bikes with efficiency greater than a good chain - then...maybe. I...

    Convert Q45 to ebike

    We definitely do not have any S40 frames that are QR still around. It has been a good handful of years since we sold through those. Robert

    Climbing

    I have found crank length to be really personal and also dependent on the bike - no matter what the numbers say for gearing, etc. You really can only know for sure if one length works better than another via some trail and error. For me - I love 150's for all things climbing and otherwise - but...

    Convert Q45 to ebike

    Trust me - the "standards" that are more and more rapidly evolving nowadays - as we get more and more into higher tech materials/processes - is really maddening to me as a product manager. Because the second something becomes the "new normal" there is already new stuff on the horizon that seeks...

    Convert Q45 to ebike

    The swap to through axles is a bicycle industry wide change not just for us. It is becoming near impossible for decent hubs to be found in QR and it is near impossible to find even one new bike made in the upright world that is QR when browsing what is coming from the shows overseas. So as such...

    Results of installing a Viscoset headset in an S40

    Yes press fit. I just remove with a brass pipe/blunt instrument but inserting a headset press is best to not damage the head tube or cups.

    Results of installing a Viscoset headset in an S40

    The stock lower cup only has 2mm of "cup" that sits outside the frame - basically just a flange - this headset was/is to keep the front end as low as possible. The lower Hellbender Viscoset looks to have a cup that sits 7.5mm of cup outside the head tube - the bearing sits inside but the actual...

    Results of installing a Viscoset headset in an S40

    I am not 100% sure on the status of the newer Viscosets from Cane Creek - or which ones are available non-OEM to the consumer market as for a time they were only supplying to OEM. There is the "Hellbender 70" version that could technically work in the lower V20c bearing race, but I have not...

    Free hub

    I am not 100% sure what model free hub the Chosen wheels are compatible with, or if those parts are even available from Chosen. Are they saying you need a new wheel entirely or they can replace to a different hub?

    Electric conversion kit / Q45

    We have one of these (FRONT hub motor) to go on the rear of a through axle Q45 at some point at the warehouse as a test case. I am expecting no issues - other than finding a good way to mount a 20Ah battery and possibly wiring lengths. I am pretty sure this has been done on the through axle Q's...

    A very nice S40 review...

    This - in my biased opinion - deserves a lot of views and likes. :-)

    My experiences with the switch from the M5 CHR to the Cruzbike V20c

    To make it easy for you all: A quick note on the M5: I've been riding the bike for 2.5 years, but haven't been able to overcome some difficulties. For example: - Slow cornering/turning on the road: There's a risk of the heel of your shoe getting caught between the front wheel and the frame...

    RAGBRAI 2025 - The Most EPIC Cruzbike Ride Yet

    Hey all, thought I would share a few thoughts after recovering from the 2025 RAGBRAI event. It was one for the ages for sure and a real great time. We had a good 27 Cruzbikers at least as there were many that were part of the regular ride that I saw on the road and various Cruzbikes parked in...

    Question on geometry and balance on the v20

    Thats probably great on your sternum when you hit a pothole. LOL. This thing rears its head every now and then for some reason I cannot understand.

    Grin now looks to have a 12x100mm through axle front hub - that TECHNICALLY could work on the back of a Q45 - though I cannot say for sure, as I have only looked at it briefly, but it looks to be the only actual through axle front hub motor I have seen so far. I am not exactly sure how the...

    Cassette

    Personally would forego the chain whip - I tossed all of my old chain whips for cassettes in the trash after getting one of these. Much more soapy: https://a.co/d/grNIAK5

    Ventisit 2cm or 3cm?

    I am pretty sure all of our Dentists are the 3cm ones. I am not sure that Bart at Dentist has done a 2cm one for us, actually. maybe a long time ago...
