Just wanted to clarify 'apparent CYC Photon overheating problems' so the game of telephone doesn't get out of hand. While I respect m@Robertson and all the contributions he has made on this site, he has an obvious hatred for CYC due to issues he had with previous products. I understand this, I...

While Im sure about the e12, I have aver 20k miles on various KMC ebike specific chains (9 and 11 speed) including two 1500W 52V BBSHDs

I would trust the manufacturer over anything Stefan states. See the linked tire/rim width chart. https://www.schwalbetires.com/media/16/8f/9b/1654668257/reifen-felgenkombination-etrto-22-en-2.pdf The only question is what is your internal rim width. You could measure the outside rim width...

CYC Photon Review at 950 miles The CYC Photon is still going strong with no major issues. The motor did come slightly loose after a few hundred miles but was easily fixed by retightening the BB cups to spec...no problems since The CYC photon with its incredible torque sensor response is by...

Stop projecting Stefan, the only bully on these forums is you, you seem to be of the mindset that strava stats make your bullying justified because you can PROVE. You behavior on these forums is typical of a stereotypical 'eurosnob' who hates the US. Why you persist with this attitude on...

I have been trying tubeless various times since 2007 and for me its just not worth the effort and maintenance required. Sure if you only have a bike or two, it might not be an issue but when you have lots of bikes like me, tubeless is just not worth the hassle. The option I use is tubes with...

Like pedaluma, I thought mirrors were for losers for years, as I get older with less neck mobility I finally gave in. If one wants a more minimalistic mirror, I highly recommend the The Beam Corky Urban, I use it on everything except my dedicated hard trails only eMTB...

Wheel size specs can be found here: http://www.bikecalc.com/archives/wheel-sizes-article.html 26x4 has a diameter of 762mm with a radius of 381mm 27.5x3 has a diameter of 736mm with a radius of 368mm So to use a 27.5x3, you would be lowering your Bottom Bracket by 13mm or 1/2 inch. This would...

While the BBSHD is a monster of a motor, well understood with parts availability its PAS is just soulless when compared to the CYC photon. Some like the PAS more than torque sensing, I ride solely for exercise and prefer torque sensing. Since building up the CYC bike, its my preferred ride...

The important thing to look at is the Max Chainring on "frame spec" tab for the ghost grappler at www.surlybikes.com. I have put BBSHDs on a Surly Troll, Bridge Club and Ogre. The Troll and Ogre only required a minimal spacer (0.5mm to 1.0mm) to get the BBSHD to fit without hitting the...

Without knowing all the details of your hills, your weight and fitness, its hard to say for sure. My GMAC rides are.were typically 20-30 miles with elevation gain of 1000 to 1500ft. Alot of 4-6% rolling hills with some 8-10% sections and lots of wind. Im around 240#. The GMAC handles it fine...

GMAC update The GMAC system has been wonderful all these years (started this thread) but I am moving on to mid-drives exclusively. Many local MTB trails have recently been opened to ebikes, while doable on the GMAC are much better suited to a mid-drive so my focus favors mid-drives The CYC...

Some info if you dont want to buy a new Brose Motor I recently sold a 2018 Brose equipped Bulls eMTB(about 4k miles) to a friend who is going to have his motor rebuilt this winter. Nothing wrong with it now but he will get upgraded bearings, better sealing and a newer stronger belt. A DIY...

Im using 180 Quad Piston Front, 160 Dual Piston Rear, no issues with clearance on the GMAC. All brakes are Shimano Deore with Metallic Pads. Im limited to 160 in the rear due to the surly Ogre Rear dropout design. I believe there is a way to move the rear wheel rearward in the horizontal...

CYC Photon Race Mode Ride Temps: 90F This ride is basically the same route described two posts above (#293) with the exception of not doing the super steep section I had to walk up before. The Photon was setup unrestricted in Race Mode with 3 assist levels (Low 500W, 50% torque, Mid 1000W...

Sorry to Pedaluma if this strays too far off topic The banter I see comming from EBRs most prolific poster is similiar to the banter I have had with the typical porsche owners at track events I participated for over 10 years. My car was a turbo miata with 270rwhp running race tires. I touched...

CYC Photon Max Assist Baseline Ride Decided to do a whole ride at max assist (800W max) on a ride I tend to use as a baseline. Distance: 17.5 miles Elevation: 1200ft Temps: Mid 80s This is a very good mix of all sorts of terrain and condition including gravel/street/rolling 4-6% hills with a...

This would also apply to anything relating to throttle use
