    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    Every shock ive ever seen has the same size eyes. 1/2" x 1/2". I thought that was pretty much universal across the industry. What does change on every frame is the width between the mounting points. And what ever hardware I had in there was the perfect width for the e55 frame. So I believe...

    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    I Noticed a small amount of clunking in the forward shock mount. I suspected maybe a loose bolt from my DIY bolt hardware. But i found that the shock hardware/spacers I had used had a bad design, where only a very small surface area beared on the shock eye bushing. Im not entirely sure which...

    Dengfu E82 | 3x3 nine IGH

    THat sounds like alot of hassles. Why dont you build your own rear hub/wheel? Its actually not difficult at all. It is a little time consuming for a first go, and perhaps a little daunting. But really its not hard. I build all my own wheels including a couple for the old Kindernay hubs...

    Chainring Guard for AmFlow PX, ideas?

    I designed my own chain guard / chain guide for my X1 motor as there was nothing perfectly suited off the shelf. I designed it in Onshape on an old Samsung smart phone, and sent the files to JLC to be CNC cut from 7075, then anodized to match my bike colour way. It bolts directly to the 104BCD...

    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    I took the bike on a long ride yesterday. Rode until 60v (3v per cell), which is where the cut off is currently set. Got about 35kms of hard riding on the 4kw tune. Technically you could run the cells down a little further to say 2.8v / cell, but i dont really see the point. Once the...

    I got the v2 104 to 130 bcd adapters today. I have installed them with a 42t bafang ultra chain ring. Initial impressiona are its an improvement.

    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    It certainly is great fun. A little bit of pure terror and plenty of adrenalin. Ive been playing around with the motor control options in the app, trying to find a good match. Motor is currently set to 4000w peak, but with the torque slider reduced to about 2/3s. (About 2/3s of 280nm)...

    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    Bikes running good. Really getting the feel for this thing now. Its insanely fast, and really gets the adrenilin pumping. Great fun to ride. I feel it kind of falls somewhere between an eMTB and an eMoto. It has characteristics of both. Handling wise, it feels eMTB. Bike feel, cornering...

    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    Its not about top speed. Its about gear ratio / pedal cadence. Remember, the CYC 5spd cassette smallest cog is 15t. A typical 1x MTB 12spd smallest cog is about 10t these days. (10t or 11t depending on which feeehub driver / cassette brand you use.) A 30t chainring with a 10T rear cog is...

    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    I got a PLA print from a friend to check fitment. You can see the gold part below which is the V1 adapter. A fair bit more internal clearance. The chain ring behind is a 42t Bafang for size comparison. This picture shows with a Deckas 44t chainring behind. The chain guide is the exact same...

    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    I have designed the V2 104 to 130 BCD adapter. This one incorporates a chain guide and spacers. Saving on assembly complexity. It has larger internal clearances to fit over the CYC 104 spider. I also tried to give it a futuristic organic look with alot of complex radius curves. I spent a...

    Conversion - Installing M500/M600 Motors in M620 Frame

    I dont think Fast nad Furious will be able to msg you. He only has 4 posts. I think there is a minimum limit before you can send private messaged.

    The Golden Goose. 72v Dengfu E55 CYC X1 Pro.

    My 104 to 130 adapter arrived from JLCCNC the other day. The chainrings fit into it perfectly, the fit clicks into place with just fingur pressure, and is snug enough to stay clicked together. The color is 'champaign', which sounded like the closest off the shelf color to gold. But it just...

    Arm pump/hand fatigue help?

    I can only go from my own personell experience with my dh38. Turning the compression down makes a noticable difference to arm fatigue

    Arm pump/hand fatigue help?

    Try reducing fork (hi speed) compression damper strength a little bit. Too much makes it jarring and ypu may find it not even that nessisray to your riding.
