Show me your Ebike silly pics

[DerekG]

In response to some of the more serious topics on the board I've decided to open one where you share a silly picture which would only make sense to ES members and then a short caption/ explanation. Mods feel free to move if you want, however, because every picture is about ebiking I believe this is appropriate
I will go first


*I couldn't help but envy all the talk about those "Cute" motors so I decided to grab one of my own. However, I confused "Cute" with cute and ended up with something a little too small. The motor which I will name the "Bad Boy II" runs at a mind blowing 12 volts DC and can even be overdriven to 16 volts ( a 4s pack :-O) for those who love to taunt death. Please note that my hand is very normal in size, making my mistake all the more evident

TORQUE ARMS!

I don't know. Those cute motors aren't that cute. I droped 1 on my foot the other day and it bloody hurt..... The axle caught me just below the ankle.. ouch, and left a nasty bruise :wink:

Also enclosed some pics of my little ongoing experiment, be warned it's not pretty :|

Notice the double 24V 9A LiFePO4 packs in series, with the controller neatly integrated for maximum aesthetic appeal 8)

But this is no trailer queen... Just fitted a cycle computer this evening and it's doing 71kph no load. Will update with real speed ASAP. I reckon at least 50kph but could hit the big 60.... We'll see

New creations are pending and I promise they will be unrecogniseable

are those wrenches attached with duct tape?

 

[amberwolf]

Looks like hose clamps--I can see the screw for the top one.

 

[DerekG]

Yea, they look like two hose clamps although it took me a few minutes to figure out if it was really duct tape as that was what it looked like to me too. You can see on the bottom one the notches the screw screws into... not sure what to call them.


Anyways, here is another one from earlier today... I decided to give myself a real workout by testing how practical it would be to actually charge the battery through pedaling. I managed to get regen above 100%, mainly to see what would happen/ if anything would blow up

Of course, I had only gone half a mile or so at this point so needless to say I realized it wasn't very practical rather quickly From now on I will let the wall outlet recharge my battery... it's much better at it

No way I'm a bit of risk taker sometimes but that would be just inviting a 1 way trip down the road, face first

That's right and thought that 2 wrenches was better than 1 in this case. Even with 2 wrenches it seems to dig into flats of the axle. Also doubled up on the hose clamps as you can see. Will be getting some torque arms made up soon as they don't seem to be available around these ways. Well I can't find any :?

I ran a very small battery with a big motor recently and overestimated my range yesterday. It was the first time I'd run this battery and thought it had failed, but now I think it was just too small. My god is it hard work pedalling a POS bike with a Hub motor, flat batteries and my girfriend sat on the rear carrier (at least she's small). It started to rain too. This just reinforces to me how great the e bike really is when the batteries don't run flat

My example just reinforce DGs last point

This might qualify as a silly pic.

This hubmotor just arrives from the vendor in China, just as you see it here with 5-speed freewheel installed. On the other side of the motor, is another screw-on mount, possibly for a disc brake... but looks just the right size for a freewheel.

Ever seen a hubmotor with the freewheel on the SAME side as the power cables? Neither have I. Not even in the pictures in the vendor's ad.

Uh oh..................

 

[DerekG]

wow... now that is odd

I wonder if you could mount another freewheel and run an rc motor from it

I'm guessing it's cheaper to produce that way but who knows... very weird

It helps if you disconnect your motor phase wires from the controller, assuming it does regen instead of freewheeling.

If I have to pedal mine with no assist, which goes thru the drivetrain without a freewheel, I have to disconnect the motor's chain because of the gearbox resistance.

No regen, it's a geared motor with freewheel. A combination of the drag of the motor, quite soft tyres to take the edge off the bumps, rear wheel bearings that are on their last legs and my girlfriend sat on the rear rack was quite enough for me Bloody hard work on that POS, oh and the left panel and crank are a bit bent too.

It's getting retired very soon or given to a good cause. Hasn't served me too bad considering it only cost about $50 retail out of a supermarket. The replacement will be much better, but still very sensible money

One of my 409 motors came with dual freewheel mounts like that. You wouldn't be able to use it for a 2nd drive, the threads are the wrong way. A brake would work.

 

[DerekG]

So you could wire up an RC motor for reverse if you wanted? More trouble than it's worth but would be funny to see.

I'll take the girlfriend if you don't want her... I'll even trade for the incredible motor in the first post

No thanks but the offer's tempting... :|

I'm sticking with her, she's a good'n
