Not at all. It's a little harder if you're a Luddite without a smartphone.

Assuming you've already copied the photo from your camera to your desktop/laptop, just open the image directly in the Chrome browser. Then just right click to get the option to search with Lens.

Looks like you have a dummy chainring functioning as a chainguard on that bike?

That is right and thanks for the tip. I took the original 110-BCD five-bolt chainring and used it to cover the all black motor. Lens is super helpful when doing things like trying to source a controller. You just photo the label with its barcode. Controllers for bikes over six-years-old are very hard to find. You might find a used one, but who knows on that crap shoot. The planned obsolescence in the industry sucks.

This is another Mike's Bikes Mega Sale $450 V7 from 2020. It had small brake pads and a black freewheel cluster, with cheap grips and a brown vinyl saddle, and skinny white tries. I installed the TSDZ2 motor and the battery. The sedate original suddenly looked kind of bad-azz. A three chord rock song with red, black, silver. For the directional Super MotoX tires I had to remove the fenders and deflate the tires to get them in. It just fit the stays. Mike's owns Public. Mega Sale is in mid-August and again in March. You can pick-up an $899 IGH Nexus, R-18 disc bike for $549. I made the long MTB pads match the bike. Those e-50 tires fly over broken pavement. I have never seen this bike since. I reused the original chainguard on the ring. The bike quietly does twice the speed of a Sefaninan.

I finished the recumbent trike yesterday. One problem was extending the speed sensor. Because of the added length I used heavy gauge wire between the battery and the motor. I am working on the Rock Hopper now.

A bike just came in. It was a referral from an adult trike lady that I hooked up with other Sr. eTirke riders. I have worked on her trike a dozen times. The bike had a BBS02 installed across town by the owner's neighbor's kid. The motor was not mounted right and the narrow/wide chainring was off by one cog. On the second ride the motor housing broke. Everything was done wrong. The levers and throttle were reversed and it was all held together with red electrical tape. The display wire had a foot chopped off it and was mounted in the middle of the top tube. The wires were twisted and not soldered and again covered in red electrical tape. I removed everything, washed it and will start fresh by installing a new motor. I will need to splice in that missing foot of wire to the display. Here is the last bit of red tape.

On the second ride the motor housing broke.

What was the cause of the housing breaking, and where did it break?

What was the cause of the housing breaking, and where did it break?

The bike has an odd down tube at the BB. No bushing or motor mount was used. There is a lump on the frontal top of the motor to one side, the drive side. The narrow/wide chainring was off by one tooth. The motor's right side housing broke across the place it covers the main gear. The owner is 14. I do not want to install a throttle on a BBS02 for a child. I will send the dad a link to take the Highway Patrol eBike Safety Class.

Edit: There is a bigger factor to the fail: I just inserted the new motor into the BB shell. On the right side there is a 6mm gap between the BB and motor with no spacers. The motor's housing covering the main gear hits the right chain stay. So, it was locked down pushing against the chain stay. That is why it cracked there. I will see if I have enough spacers.

What a mess! Some people just haven't a clue.

It is ready!

I installed the throttle but used marine grade heat shrink over the connector with a Schrader dust cap imbedded. Then I painted it with three odd colors and adhered a PedalUma sticker to it. It cannot be tampered with and be made to look like nothing happened. It will be up to dad to cut it off when he thinks his son is ready. The thing can be ghost pedaled anyway.

Update Edit: I just had this conversation with the kid. To him 'normal' is for a kid to do 35, 56kph, on the street without pedaling.
Zach,

It is normal and legal, yet fully programmable for when you take it to a private ranch. I am not going to walk you through on how to jailbreak to make it illegal. But that stuff is all online. I hope you understand.

Thank you,

Rick

Well let's hope they are satisfied.
A trick we amateur radio operators use with connections in open air feedlines is to put the heat shrink over it and then shrink up just the tip of one end. Then we inject silicone into the other end until it's full and proceed with the shrinking from that end we began with. When I get to the connector I switch to the other end to ensure there is a reasonable layer of silicone surrounding the joint when it's finally sealed up. These are joints with screw connectors and there is no danger of the silicone bleeding into the electrical connections themselves, so with a push in socket it might pay not to put the silicone under too much pressure.

Disassembly is simple because after you cut away the heat shrink the hardened silicon log picks and pulls off easily.
