Re: The end of BionX?

I'm a small but longtime Bionx dealer. Bionx unveiled lower wholesale pricing for mid 2017 and later pre season orders as well as open stock through Bionx Ca or Hawley (their US distributor). They had planned to announce a $500 retail price cut on all kits on March 1 2018 which allowed current deale...

Re: BAFANG MOTOR INSTALLATION PROBLEM

When I installed mine on a BD bike, I had to spend about 30 minutes with a half round file to remove aluminum from the inside of the shell. I think during welding the center of the shell sagged a bit (best I could tell). This prevented the bafang from sliding through. Some careful file work solved t...

The rim is double drilled. 64 holes, two rows of 32. All spoke holes in the hub are used, only half of what's in the rim.

Re: Saluki - wheel lacing

Lacing to one side allows both drive and non drive spokes to exit the hub flanges at an angle towards the centerline of the hub while also offsetting the rim 28mm to the non drive side. This moves the cassette (Freehub) outside of the confines of the 100mm wide rim (and even wider tire) such that th...

Actually, his half link chain is symmetrical, so there is no wrong or right.

However, I would reverse the direction that it travels, generally the outer link leads the inner link.

Re: Why is my BionX so buggy?

The weakest link in the Bionx system is their throttle and the tiny wires it uses. They get pulled or pinched and have connectivity issues. I would suggest two things: 1). If the shop has the Bionx Bike Interface (hardware/software tool) have them update your system to the newest version. 2). Purcha...

Re: Saluki - wheel lacing

It's a Surly Moonlander frame. It has an offset rear (28mm) as engineered and required by the necessity of keeping the chain clear of the tire while still being able to hit all the cogs on the cassette (and still use a 135mm wide hub). You can't just put a 135mm hub in the center of a 4.8" wide tire...

One of the nicer freewheels out there will be the IRD Defiant freewheels.

For chains I like the SRAM PC850 or PC870.

Yep! CST is the type of gears you have on the rear of your bike. there are 2 styles of rear gear used. Freewheel, which is what most of the world still uses, and most motors come equipped for, and CST, which is what most North American bikes made in the last 15 years use. They aren't compatible wit...

Re: New Bafang Crank-Drives

I've burnt out three 750w controllers. I've not ever heard of the other smaller sizes failing. Bafang dealers with the bafang software can program the controller to lower the maximum amp draw a bit. This doesn't affect performance notably, but does increase the life of the controller, from what I'v...

Re: '91 Rockhopper seem right?

Old steel mountain bikes make excellent e-bike frames, IMO.

For hill climbing, I do believe a geared hub motor would be a better choice than direct drive. Alternatively, a mid drive (powered crank) uses the bicycle's drivetrain and thus gives you the full range of gears at the rear.

Re: Epic rim failure. Why?

As a bike mechanic, my opinion is that ebikes need fatter tires in general. Especially as speeds increase. Larger air volume decreases the spike loads from hitting pavement lips, curb edges, potholes, etc. Ebikes also need to be inspected regularly. If indeed there was galvanic corrosion at the nipp...
