Woodytx, just so you know an ebrake is just a way to instantly cut power when you touch the brake lever. It has nothing to do with an electronic brake or anything like that. Not sure if you understand what an ebrake is?
I do, preventing surges etc, but my non-fancy brakes easily handle those. I am a huge fan of e-bikes but have found that electronics around braking and shifting don't add to the experience, they just add complexity.waynebergman said:Woodytx, just so you know an ebrake is just a way to instantly cut power when you touch the brake lever.

This should explain your problem and how to fix it.

more important is the built in off set in the bling-ring to make your chain line up.
Dogboy1200 said:Which 42t chain ring from Luna? They offer 3 different ones. There's the eclipse, the Lekkie bling ring and a new inexpensive one they just started offering. I have all 3 and they all have different offsets. Sounds like you have the inexpensive one. It's listed as having the same offset as the stock ring but it really has less. This one doesn't work on my bike (can't use 1st gear). The other two have similar offsets to each other that are greater than the stock ring and on my bike they have too much but in my case they work perfect with the spacer Luna sells separately.

and how is the ring but together on the spider if it bolted together maybe taking it apart and putting some spaces washes to off set the ring to left?
Won't work. The chain ring would hit the gear cover then. Get the Lekkie Bling ring. The teeth on the Eclipse are very long and I had some problems when the chain got muddy it would try to stay engaged with the chain ring and ended up jambed between the chain ring and swing arm.Esting said:I am looking the pictures of your ring gear on Luna web site

Hey Dogboy is there a chance you had the skinny part of the chain mounted over the thicker teeth instead of over the thinner teeth. I have found the eclipse ring to work flawless, it is awesome. You may have other chain issues like tension or something else to blame but not the ring. Just my opinion......wayneDogboy1200 said:Won't work. The chain ring would hit the gear cover then.

No I was careful to get the chain right. Later I actually ground a little off every tooth to make their length the same as regular chain rings and then it worked fine.waynebergman said:Hey Dogboy is there a chance you had the skinny part of the chain mounted over the thicker teeth instead of over the thinner teeth.

Foregoing the spacers on the drive-side means the BBSHD is 5mm off-centre, toward the non-drive side. Is this a big deal? If not, then I think my problem is solved, aside from not being able to access the first gear.

Your thinking is backwards. The 73mm kit is perfectly centered in the frame only on a 68mm bottom bracket (oddly enough) when the drive side is snug against the bottom bracket. Measure your crank arm to rear stay spacing on both sides and you'll see.
With the spacer under the drive side, your kit is offset to that side (and higher gears) a full centimeter. To properly center the kit, you have to put the 5mm spacer on the non-drive side, directly under the motor mounting plate. If you have front chain ring clearance in this position, it is likely the most ideal chain line as well.
I just did an installation on a 68mm bracket, but only had a fraction of a mm clearance between my Luna Eclipse chain ring and rear stays with the spacer under the mounting plate, so I opted to use one 2.5mm spacer on each side to gain chain ring clearance, and live with the 5mm of crank/frame offset. My chain line is almost ideal in this position as well.

The BBS02 Gen 2 units look the same from what I can work out....
