That is a big bummer. Dealers are not allowed to open the motors and repair inside and they do not have the skills or parts. All they can do is order and sell a new motor and bolt it on. This is why I have spare parts such as clutches, torque sensors and cadence sensors. The ToSeven factory gave...

Welcome @tsmyther. After my divorce I visited my cousin in Boston and we rode bike everywhere. When I got back to California the first thing I did was buy a bike and get into the industry and started repairing friend's bikes. Then I wanted an eBike I could not afford. So I made it. I have been...

I use those Drift Mechanic "Maniac" freewheels all the time. They are beautifully polished nickel plated, are not expensive, and come in 11-34. They are so much better than the Tourney ones that come as original equipment on so many hub-drives. It just requires a mid to long cage derailleur. On...

Mine are the banjo shape. And you are correct in my opinion about mechanical brakes made from a solid block. I hear that bike packers out in the middle of nowhere like Peru or Kenya, prefer quality mechanical brakes. To bleed I also like push-pull. I pull out the old burnt oil down until I see...

I am so glad to be helpful. That is exactly what EBR is all about. What is in it for me by helping others? I get to work on real life case studies. So, when I encounter a problem I already have experience. And it is all with free peer review.

The Hase mechanical brakes are like jewelry and very strong and with great action. If coupled with highly polished stainless cables with pure silicone oil inside the housings, you have a simple system that will never need a bleed or form a vapor lock. Those Avids in my opinion with the little...

Me too. Having both pressure and suction really works to force it through. I fantasize about using DOT 5. It is used in race cars and is super stable. I just don't know how it will impact seals. It is supposed to inert. Really good mechanicals are really good. Just tighten the inside pad after...

Bleeding a bike can be such a mess. Get cardboard under it. @Aushiker, It was about 14 years-ago-working a 9 to 5 selling wine; when I was at a picnic table eating a tuna sandwich from home with two ladies from work at lunch, I explained that I could not work on things with rubber gloves, I had...

What is so very cool is that that 2018 conversion still has a perfect battery! Some major brands make you spend $1000 every two-years for a new proprietary battery. They are made to fail, so you keep spending until you give up and buy a new one. Putting it that way, he saved $4,000 dollars so...

Yes, the caliper comes off with the pads off, and the caliper is on or over cardboard away from the rotor. Pull the old dark junk oil down until you hit fresh oil from the top dispenser added reservoir or syringe. Dispose of the burnt junk. Then go the other way with fresh oil so no bubbles...

Start by watching Jurassic Park.

I have recently had to do brake bleeds on things such as gigantic cargo bikes and eTrikes. It is such a pain. This is where you can share your pain and pick up useful real world tips from others. One eTrike took two hours to get all the bubbles out. I just purchased these large 200 ml syringes...

The easy way is to get a second spoke magnet. Remove it from its case, often plastic, and double stack the magnets with crazy glue. Some pickups have a red light that flashes when the magnet passes. The gap should be about 2.5mm. But by double stacking you increase the power, so you can get away...

The dealer can log into the Specialized Dealer app, enter the serial # and hook the display to a PC and update the firmware. Then they can run the diagnostics. Sometimes the app will ask to pedal it at a cadence of 60 for one minute to see that all is in sync. Then it will say to check x, then...

I would advise getting a half-hour of diagnosis from a dealer. Many do not have a clue, and will just want to sell a new bike, some are very good and have diagnostic tools with factory support.

I am all for bikepacking. I am just a bit concerned about the topic of a moron's g-spot.

Welcome! I also want to see a photo of the conversion. I have one in the workshop that is going out today. I did the conversion eight years ago and it finally came back for an new chain and an internal transmission lube. This is the first one that I made all through frame. It brings back memories.

Could it be battery sag? My local dealer cannot check this because they do not own a voltmeter. And they claim to be the county's 'Premier eBike Shop." When is the last time you checked your battery. Was it ever replaced? When was the last time you lubed inside the motor's transmission?

I have an inspection in a half hour or would create an image of a crotch with an adjustment screw in it. As the screw goes in the crotch spreads.

AI Overview A "crotch screw" is located in the crotch/angle where the lever blade meets the master cylinder/body, changes the resting distance of the brake lever blade relative to the handlebar grip.
