Re: EVG eBike - Heinzman 36v 500w barely runs

it doesn't have to be stainless and it doesn't have to be steel. it can be copper wire and you can drill the hole just big enuff to jam the wire in and then use a punch to drive the wire deeper. i think we tried to talk someone into tack welding it but she had it drilled and roll pins inserted. but...

Re: Making a bike alarm with remote warning

I picked up one of the A B C alarms. under $4. Looks like it does work, but crooks will figure them out quickly. The alarm is rather wimpy. Also, picked up a remote vibration alarm. seems much better since it can be hidden. $6. There is a YouTube video with the alarm removed from the case and put in...

Re: EVG eBike - Heinzman 36v 500w barely runs

don't drill if it gets to that point. just 'stake' it with a punch. drill filings will get into the bearings no matter what you do. way cool you fixed it though. The FIX lasted about 2 seconds. Either the wrong "bearing adhesive" or too much contamination. I heard a "pop" and th...

Re: Temp sensor that's too cool not to share

How high of a temperature will the LM35 sensor take? I need to build a temp sensor for my eBike and my Motorcycle. I have a couple of temp sensors I bought off eBay in the mail. The sensor from Hobby King looks like what I really need. http://www.hobbyking.com/hobbyking/store/__9744__Hobby_King_Volt...

Re: EVG eBike - Heinzman 36v 500w barely runs - large gear s

Right or wrong, this is what I did. 1. Duct tape the bearing dust cover and caged roller bearings. Added grease to needle bearings. Cut gap between race and one-way clutch inner race. 2. Spray brake cleaner on the race / one way clutch gap (between blue and black arrows). 3. Turned so it would drain...

Re: EVG eBike - Heinzman 36v 500w barely runs

if i were you and there is no grease on the interface then i think you can just dribble it on a little at a time around the edges and just let the solvent in the bearing retainer sweep the oil off the faces.if you use solvent it may spread any oil in there out all over the entire surface so just us...

Re: EVG eBike - Heinzman 36v 500w barely runs

Thanks for helping.

My plan of attack.
1. Duct tape the bearing dust cover and caged roller bearings.
2. Spray cleaner on the race / one way clutch.
3. Let dry.
4. Put in Loctite 640. Tilt so any leakage goes away from roller bearings.
5. Assemble and test the next day.

Re: EVG eBike - Heinzman 36v 500w barely runs

did you try the bearing retainer like i recommended on the other thread? can you pull it apart to clean it? The other tread drifted between fixing two different types of hubs, or so it seemed. The bearing spins on the race, but will not pull off. I guess I could get an automotive puller or bearing ...

Re: EVG eBike - Heinzman 36v 500w barely runs

Yes it should be a tight fit between the black and blue arrows. A geared motor will always have noticeable drag when rolling backwards as the oneway clutch will engage and spin the motor. That is my problem. The one way clutch spins on the racing. (Between the black and blue arrows) Need to either ...

Re: EVG eBike - Heinzman 36v 500w barely runs

It looks like the problem with my Heinzman hub is the "bearing / one way clutch" is spinning on the race it was pressed onto. If I am correct in my understanding, I need to make the assembly so the inner spacer (blue arrow) does not spin on the sleeve (black arrow). This may require cleani...

Re: Heinzmann disassembly

I finally got to talk to a human at Heinzmann ... No spare parts in the US. Basically, you send it back for warranty work, or you get to replace it. No repairs. The gear is just press fit, and it is not supposed to turn in place ... ever. He suggested either having it laser welded in place, or pull...

Here is a photo of my hack job. As you can see the gear is toast. I succeeded in getting it off though, and the CSK20 too.
I have the same problem. The motor works fine, the gear just spins. Is there a way to remove it? I noticed the phillips screws.

EVG eBike - Heinzman 36v 500w barely runs

I took my EVG bike out for a test run and the motor runs, but there is no power to the rear hub. Gear issue? The bike is used and the rear hub has always made a slight click. (Not the freewheel.) The bike ran strong for me, but my step-son said it was really slow the last time he rode it. I noticed ...

Re: I picked up a 24v Lee Iacocca EVG Ebike

I have been playing with the EV eBike. For now, I will stick with the SLA batteries. I like the simple, plug in charging. Has anyone created a 5 or 7ah backup 36v pack for the rear rack? It would be nice to have as a reserve if the batteries fell short on a ride.

The battery packs with built in BMS seems interesting for bikes.

Thanks for the reply. I'll check the brake controls again. See if it is the connection on the other end. The seat, I'll probably replace. The wiggle is just annoying. It's a SX and a pretty nice bike. The forks seem pretty stiff, might need cleaning. Another "To do" item. If I get another ...

Re: Temperature inside hub motors - choosing a thermal fuse

I like rc onboard temp sensors best because of how small and light-weight the display is. You want it light so you can just sticky it to your handlebars rather than having to devise some kind of wacky mounting apparatus.

There is a need for the type of tube clamps that will allow connecting a battery compartment to a bike triangle. Some bikes have a section of tube that is somewhat triangular in cross section. Others are oval. The easiest tubes to home-fabricate clamps to are circular and square/rectangular. I'm th...

OK, now I get it. I picked up a 36v Lee Iacooca eBike today. It showed fully charged, so I rode it around on full power. I'm 210 and made it about 6 miles.
