Re: how fast does 1600 watts get you on a mountainbike?

Re: Specialized Stumpjumper conversion recommendations

Good discussion here on battery size for mt biking...https://endless-sphere.com/forums/viewtopic.php?f=28&t=111282 The consensus is that a ~8ah battery is sufficient for most riders and most rides. Going with a big (15ah+) battery adds considerable weight and cost. Not sure how much time/effort...

Re: Specialized Stumpjumper conversion recommendations

LOL... yes! Been there and done that, but not from a fork compression issue. I really need a longer travel bike front and rear. I had this bike around and it was still in good shape so I converted it. But to really explore the motor's potential in the rough it'd be nice to have at least a 150mm bik...

Also note, don’t use a seat stem mount for your battery especially with off-road use.

Re: Specialized Stumpjumper conversion recommendations

Howdy. I have the same bike as in this video and would like to do a conversion: https://www.youtube.com/watch?v=7qO1Yuj3sH4 However, there are few issues with this frame. One is that due to the frame shape a mid drive motor will need to hang down causing loss of ground clearance. Also I'm not sure ...

Re: Specialized Stumpjumper conversion recommendations

CYC_Installed.jpg Well you have a decent fork on there but you need a longer travel fork. I just fixed the same situation on my bike by installing a downhill fork. It can be quite dangerous if you compress the front fork all the way and it bites down on the tire as you will go over the handlebars. ...

Re: Waterproofing exposed switches?

connections with Vaseline though Nice tip! I’ve used silicone in the past to seal up connections. Vaseline trick is a great idea. Squirt them with WD-40 once in a while. WD stands for Water Displacement. :thumb: Nice, I wonder if silicone spray would work the same since it doesn’t stink as bad lol

My led lights only pull a few watts. Unless you are running other types of lights it should not get hot.
Right, same here this one pulls around 25watts.

Since these DC to DC step downs or so cheaply made, I was suggesting since it’s not heating up it’s a good sign it might last.

Re: Does this look safe?

If SAFE means it won’t set fire to your bike, this is about where you plan to place it. It can be installed perfectly safe. If SAFE means reliable, forget that kind. You need to put more money for a good, reliable DC/DC converter. The only other step downs I could find were way too big. I’m hoping ...

Re: Does this look safe?

Well I just tested the step down and it works great. The output voltage is 11.7, perfect!
I will go for a night ride and test it out to make sure it doesn’t get too hot, the step down.

Thanks for the input guys! :D

Here’s a picture of the light installed on the bike. Not bad for under 30 bucks
I made aluminum bracket that screws into the bottom of the steer tube. I put a star nut in the bottom side of the steer tube for an anchor.

Currently stepping down 72v to 12v for lights with this. 41sHdfFNHcL._AA200.jpg Automotive grade, water restraint and potted. Would still point the wires down.

Just mount it so it stays dry, but in a little box so the heat sink can breathe. Or maybe just tuck it under the seat.
I should be able to find a place for it in my battery cover. Well it’s an ABS plastic case I made but it has a little bit of room for storage.

Re: Are fans needed to cool down battery packs?

What type of battery do you have hard case or soft pack? How much current are you pulling?
Normally the wind is enough to cool battery packs off if they’re not being pushed too hard.

Well they’re nice looking switches! 😅
I think it comes down if you ever ride in the rain or not or if this is a commuter. I have non-waterproof switches on my bike but I never ride if it’s called for rain. Can always carry some gorilla tape and if it ever starts raining just cover the switch up lol

Does this look safe?

Does this DC to DC step down looks safe? I’m trying to run a 12v headlight and plan to connect this step down directly to the battery.

The input capacitor shows 100 V and the output capacitor says 35v. It’s rated output is 12v 3a maximum.

That little heat sink though lol
