    If you mount in the triangle use the strap. Otherwise the motor will move back slightly under torque and tighten those B.B. cups to a point they’ll never come out.

    Tangent 6kw fat bike components

    Your build is close to my heart. I actually begged Dave for a 100MM adapter years ago and built the first Tangent powered (3KW) fat bike. These days I'm running a 6KW Tangent All mountain setup. I've tried all kinds of gearing combinations with these bikes, and have a pretty good feel what...

    will KMC Kool Knight Chain fit on regular bicycle sprockets?

    I ran some BMX half link chain for a while and it worked fine. Super heavy stuff. https://www.amazon.com/KMC-HL710L-Half-Link-Chain/dp/B003UPZF7A/ref=sr_1_1?ie=UTF8&qid=1523798570&sr=8-1&keywords=bmx+half+link

    Anyone know what to use for the Cycle Analyst shunt value (under calibration) in high power mode? Is it 1.0?

    Dave's 80:1 RC mid drive kit build log

    So I've been riding around with my Cycle Analyst limited to 990A for a few rides by accident. Seems when you switch to "High Power" mode on the Cycle Analyst it multiplies the amp limits by 10. Luckily my pack is only rated for 140A and the Cycle Analyst recorded only 158.8A (8200W) as a...

    I think Luna uses the 30Q in those.

    Here's the link to the stainless steel narrow-wide 30T or 32T rings from Wolftooth. https://www.wolftoothcomponents.com/collections/stainless-steel/products/104-bcd-stainless-steel-chainrings Fair warning, the 32T is your best bet. The 30T will work fine too until the chain does one day drop...

    Dave's 80:1 RC mid drive kit build log

    I haven't used the smaller wolftooth chainrings (74bcd), but the 32T ring I have installed now is much much stronger than the SBP 24T Dave sent me. I mangled the teeth on that thing in 2 rides and had to take it off when it wouldn't hold a chain anymore. I've also used their aluminum 42T...

    I get about 400 miles out of a raceface 32t aluminum narrow wide. It’s not even totally shot when I replace it. I recently switched to a stainless steel drop stop 32T from Wolftooth. It’s the only steel narrow wide I know of. 100 miles or so on it and no signs of wear yet.

    That’s really cool how that’s incorporated into the gear housing. 1000th post woohoo

    Dave's 80:1 RC mid drive kit build log

    Problem is, after a while, either the chainring or spid r warps slightly and the chain tension changes as it makes a full circle. You can see this when you pedal the bike up on a stand. The chain tensioner will actually move up and down a bit as you spin the cranks.

    I would have gone with a longer mount myself so I could mount the ESC on it. I’d love to be able to add a cooler to the ESC and run a few more amps. When using the template of the longer mount it looked like the rear shock might pivot forward and hit the gearbox housing.

    Dave's 80:1 RC mid drive kit build log

    Yes they are custom sized to fit in the frame by our man Dave D. I'm not sure of the dimensions, but I will say the super short mounts are both a gift and a curse. The PRO is that they are short, look cool, and fit just perfectly in the triangle. The CONS are that the mounts are too short to...

    I've got mine (which only spins at 275 rpm) lined up with the 15/18T in a straight chain line. Also, I'm very happy with the combination of the 32T Wolftooth stainless steel drop stop chain ring up front, and SRAM EX-1 cassette that uses hardened tool steel in the back. It's an 11-48...

    If that’s white industries or a sick bike parts freewheel it’s reverse threaded.

    Pretty sure when I took mine apart there was no grease inside. Grease can pack into the notches and behind the pawls and cause issues. I think these brown freewheels have normal right hand threads and unscrew to the left.

    Project Dauntless - My Tanget build

    Having ridden both the 3KW and 6KW Tangent for a while now, more and more I'm leaving it in one gear for the majority of the trail riding. If your drivetrain can handle it, and mine questionably can, the big Tangent doesn't mind launching in a higher gear with tons of load. I still use the...

    Tangent Ascent Charge Cooker Maxi 2.0

    That’s a cool build. I like the Luna lander fork on the front. Raising the front end makes pedaling more efficient but lifting the front wheel is easier. Not a bad trade off for an ebike. At 30 mph speeds and rough terrain my bike begged for front suspension. The ended up swapping the motor to a...

    Project Dauntless - My Tanget build

    Some good choices there. I'm exhausted at the moment. Here's the bike Dave and I were tossing around. The GG DH DH seats always tilt back like that. You can adjust them to level for ebikes though.

    Project Dauntless - My Tanget build

    Hey, it's Cuntrover from Reddit. I'm not going to go to in-depth here, but I'll help you along the way. The first thing you wanna do is get yourself a BEEFY bike. The 6KW Tangent even geared at 20:1 reduction will pull the rear swingarm of my Airborne Plague over to the right like 2-3 inches...
