    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    Thanks for the kind words! Totally agree that consumer eMTBs are pretty astronomical in price for the latest and greatest tech (although right now, depreciation is hardly a thing for eMTBs!). EX-E and Relay are both amazing contenders, and ride great. I do get much more power from my build, but...

    Thanks for the data point! Good to know you're doing it successfully. I do fully charge and balance for each charge cycle. I suppose it's worth trying - I have the materials needed to do it. This is great, I'd rather parallel than series for many reasons.

    Fair enough, I could switch to a BMS with a shared charge/discharge port. What's an ideal diode? I thought that was a mental model to use for calculations, is it an actual type of diode as well? Wondering how I'd test if my separate charge/discharge ports are really behaving this way... Also...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    Thanks! My concern is that I do want to push these cells at their MCC, since the controller can take so much. The solution here is probably to just make smart choices in BMS output ratings, which I should just go ahead and do. In the previous post, I'm just ruling out a parallel config without...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    Wow, it's been a while! I have small updates and then next steps: I removed the winter camo livery from the bike and took it to Red Rocks in Las Vegas: Those rocks are gnarly and left me with a real bad pinch flat! WHAT'S NEXT: I'm starting to think about a range extender. It's not really...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    Thank you kindly! Much appreciated, clean is what I'm going for haha There's not room in the shock cavity, the shock movement uses all the room :( I've considered enlarging an existing hole at the bottom of the frame (a mounting hole I don't use anymore), but it's hard to justify cutting into...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    Okay I upped my Street Mode to 500W instead of 250W and it completely changed the ride. Now my lowest assist setting is too powerful to not ghost pedal! I think I'll set my lowest assist setting back to the original setting and give myself the option of upping all the way to high power on...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    You're totally right. My last post was a brain-dump riddled with logical holes that I hadn't worked through yet. I have the 11/53 gearing, which is the lower torque / higher speed gearing. Shame on me. I haven't found a 10t 219H B-type sprocket that would fit my motor shaft, and I'm not trying...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    I rode my build side-by-side with a Specialized Levo SL this weekend. My takeaways were that my bike feels considerably bigger (in suspension travel, frame size, and weight) and that the SL feels like the motor puts out considerably more power than mine. The second takeaway really bugs me. I...

    Update on the cable organization: I found some offerings from some bike companies that I might try instead of designing my own. Jagwire alloy guides at Jenson...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    MONEY TALKS (how much did I spend?) This was quite a build - I dug into my credit cards for a bit on this one. Below is a screenshot of the cost tracker that I keep: Takeaways regarding money: For a performance mtb build, the frame is by far the largest cost. I don't think I overpaid - the...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    FIRST LOOK ...And here, we catch up to present day! I installed the battery according to the SOP that I created in my head - it's very regimented now. I tweaked a few settings in the CYC and ASI apps (battery voltages and thresholds, assist levels, and speed limit so far). I've been on a...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    Did the location, thanks! I have the DD casing for the extra weight and gnar, and sealant inside everything. For riding here for several years, no problems even without the DD casing. (I hate tubes) Thanks! Hey, part of the reason I'm posting this is so others might get the idea to do the same ;)

    Kona Stinky Restore

    This pack is so clean! How do you think about vibration damping?

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    I did! Only around the block. It wasn't enough to get good confirmation of the specs. Here's a pic of the taped-in pack: Reasons I was okay with no real-world testing: I'd need to climb mountain bike trails for a good test. Without vibration damping and final install? Hell no, I fall too much...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    THE BATTERY, PT. 3 - FINAL INSTALL In my head, the final packaging needed to accomplish multiple things: General waterproofing (not looking for a submersible battery, but no exposed metal) Strain relief for wires Vibration dampening (high and low frequencies - riding at speed on singletrack...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    THE BATTERY, PT.2 - SHIP IN A BOTTLE Here's a bunch of nebulous and disorganized thoughts that I was working with: I found (through hours of taping cells and fitting them inside the downtube) that I can fit up to 8 cells in one segment through the SWAT opening I could fit 20 total cells...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    THE BATTERY, PT. 1 - FITMENT Like I mentioned - I want to fit my batteries into the downtube SWAT storage. The ultimate goal here is that while looking at the finished bike, I WANT TO WONDER WHERE THE BATTERY IS. I've never been excited for a packaging project before, let's do it! I spent a...

    THE MOTOR I'm using the Stealth Gen1 from CYC. It replaces the crankset and fits into the BB, with a big hunk of a motor hanging off the front via a few brackets. Replacing the crankset lets the motor system align to the BB, which is great. However, in the spirit of adaptability to any bike...

    eMTB - Specialized Enduro with CYC Stealth (aka The e-Duro!)

    Just measured, actually! I don't have a reference with the actual 29" rear wheel, so I'm looking at the delta between mullet + stock suspension vs. mullet + WRP link. See below pics, looks like about 1/4" or ~6mm. Measuring to the center of the BB: Mullet with stock suspension: Mullet with...
