CYC PHOTON

[hindesite]

Ah, thank you. I didn't realize there was a second air gap. That seems like a poor design. That explains it.

It is not a poor design; it is a valid design choice. You get to reduce the size of the motor while still producing decent torque. The trade off is reduced cooling. Which is not a problem for the Photon in my experience.

 

[raylo32]

Exactly. This Photon's primary design criteria was to function as a light weight pedalec with good torque. Goal achieved. Personally I would like to have a motor that was also able to be thrashed around on throttle if and when I want and I would be willing to have a somewhat larger package to accomplish that. Maybe that will be the Proton? And if that is where they are heading I hope the motor won't be a huge lump like BBSHD, and if they are aiming for a relatively compact design there still may be some engineering challenges to make this work.

Toseven dm02 is only slightly larger and dissipate heat much much better than photon. CYC photon is basically a 500W (sustained power) motor while DM02 could be easily treated as 750W. No Idea why CYC charges $1000 for this motor instead of $500.

 

[raylo32]

I am keen to try the ToSevens... once they show that they have the torque sensors working properly... and if what you say about heat management turns out to be true. I also need to better understand how these are programmed and the firmwares updated. The CYC guys have made this dead easy with the app. Much easier than using the ST programmer for TSDZ2 firmware and programming, either for factory or OSF. Yeah, I can do it. But I'd rather not go backwards to all that.

Is there a diagram that shows the design? I'm trying to picture/understand the second air gap.

Took my newly Photon-equipped bike for its first ride today. Worked great; it's a winner!

It's nothing like my 140 hp motorcycle, but makes riding a bicycle a hell of a lot more enjoyable while still getting a workout.

Damn, my motorcycle has only 96HP. Triumph Tiger 800.

Mine is also a Triumph - Speed Triple R 1050. Fun bike.

This video might help. You can watch the motor casing get taken off and see the rotor underneath. I've attached a crappy blurry screenshot of when it is taken off. You can see the casing in the left hand and the rotor in the right. (The rotor being the black part that is the leftmost part of the piece in the right hand) Unfortunately they don't remove the rotor itself to make the stator visible underneath though.

Come back after 4000 km... Let's see how reliable is that new torque sensor! Btw. I Hope you are not using throttle...

 

[raylo32]

I use the throttle but only for short periods watching temperature for fun and to beat traffic situations and it works fine. Drives my bike 35+ MPH. No, you can't do thins continuously like a BBSHD, but that is just fine with me for this motor class.

I tried the throttle just to see how it worked, but not really my thing.

 

[raylo32]

Set your Photon up for "unrestricted" and try it. It is fun... and great to synch with traffic to make a move over for a turn now and then. But don't get addicted to it!

If I want to go fast I ride motorcycles. They're as addictive as heroin! My newest weakness is naked sport bikes and a supermoto - sold the Ducati crotch rocket and the BMW.

 

[raylo32]

I always wanted a Ducati Hypermotard... but was smart enough not to go there. That's probably why I am still alive! Plus I had my knee replaced recently and am on a forum for that and there is one poor guy who crashed his motorcycle and doesn't have enough of his original knee left to get a standard replacement. He has to get this special one that will still leave a good bit of disability.

The best and worst day of my life was when I took delivery of my Monster 9... only to sell it 6 months later when my daughter was born. Figured I should stick to just one potentially deadly habit, not add commute to the possible ways to miss her graduation. I still miss riding it like I stole it, but raising kid 2. Still being fairly sane in my hobbies.

I am kicking around taking an old dead bike and seeing if I can make a fire stomper of an e-bike.

 

[raylo32]

I am on the other end... still easily physically able to ride the motos but too old to take any falls. So, I may sell mine soon.

[raylo32]

Not really about just going fast since no e-bike will ever feel fast to a motorcyclist. Even on my X1 bike at 45 mph I am wanting more. LOL. But it does come in handy for me to make left turns on some busier roads where I can accelerate in the bike lane to equal car traffic speed and then merge over to the left turn lane. You can do that at bike speeds most of the time but the opening are fewer and harder to get into. And sometimes at bike speeds you get shut out and have to stop in the bike lane, wait for traffic to pass, and then try again. The throttle eliminates that. As would a 50t chain ring that could pedal at 35 mph.

I've been riding motorcycles for 45 years and believe that most people should NOT ride them. Most people learn from their own mistakes and you can't survive too many of your own mistakes on a motorcycle.

But, statistically it's still safer than getting fat, or flying gliders.

 

[raylo32]

Yup. I've never had a crash, but you can't control cagers, especially the old left hooks when they turn left and cut in front of you because they "don't see you". Many moto guys die that way.

True, but those risks can be minimized.

1. Attend motorcycle safety classes (learning from other people's mistakes and techniques for avoiding accidents).
2. Always think about what you're doing.
3. Don't ride impaired.
4. Don't ride at night.
5. Wear all the gear all the time.
6. Do a race track day once in a while to hone your braking and cornering skills.

 

[raylo32]

Did/do all that... except for the track day. That's why no falls or crashes.

Hey triple crew! I've got a daytona 675r so your bike but with the plastics, lovely engine! Previously had a FS570 supermoto, should have kept it...

Really love the triple - nice balance between the torque of a twin and the power of a 4. My sumo is a DRZ400s with two sets of wheels - knobbies on 21/18" for the dirt, and 17s for the street.
