Re: Does anyone make "small" 52v batteries?

If you're worried about frame clearance, bafang usa direct has a pdf you can print out to check the sizing: https://cdn.shopify.com/s/files/1/0537/7176/3911/files/Mini_Shark_Battery_Template_Printout_Ebike_Essentials.pdf?v=1619116147 https://bafangusadirect.com/collections/all/products/copy-of-48v-1...

Re: In frame battery housings, suggestions please

I currently use 5 rivnuts per box which is a great solution. The door/side panel closure is a challenge when it comes to trying to not to have any hardware poking into or running through the housing. Neodymium magnets aka rare earth are extremely strong. I use 2 tiny ones to secure the access plate...

Re: In frame battery housings, suggestions please

This is extremely ghetto compared to yours, but I made a bracket with 2 rivnuts that attaches to the factory water bottle holders. The bracket on the box then mates to that and is secured with 2 1/4-20 stainless bolts. https://i.imgur.com/LVGyrQu.jpg I've seen hose clamps used but those aren't a ver...

I ride in snow and heavY mud for 6 years now. I have to wash bike 100x per year with garden hose. All i did is silicone + rubber battery motor connector. No problems with original bafang display or anything else. Dont complicate things.
Are you washing the display directly?

Re: Surly Instigator: Steel frame HT + Bafang BBS02 Mid-drive

Found a shop in NM that shipped me some new 'old stock' Dirt Wizards at a reasonable price. I like the compound and tread pattern on these tires but even though the bead seats very nicely, I don't think these were designed to run tubeless. Sidewalls are fairly thin so I hopefully don't pinch flat th...

Re: Wet Conditions BBSHD Strategies?

I'm not too worried about the motor, it seems pretty tight; I have no problem washing it with a [low pressure] hose. I would not want to submerge it though. I've put a dab of RTV silicone around the cable connections and wrapped them in electrical tape so they are relatively water tight. The battery...

Is the chain sized correctly for length? If it's too long it's possible it doesn't have proper tension.

Re: Surly Instigator: Steel frame HT + Bafang BBS02 Mid-drive

I was wondering about this too. I've had some fairly burly, not-too-ancient 26", long travel MTB's. When the 650B/27.5 interest arrived, none of those frames would accept a 27.5 tire/wheel of any usable off road size...hence, 27.5/26 mullets which worked great. I thought I saw something in one...

COAR, I have no beef with mullets. I've run a 27.5/26 setup for years. My Fox 36 and dual crown fork both accept 27.5. A good while back I even ran a 29/26 setup on a Maverick ML-8. I'm just curious about your take on the availability of good 26" rubber. While not as abundant as the now more c...

Re: CF or Glass Fiber over PVC Pipe

You can bend PVC by capping one end, filling it with sand that has been heated in an old oven, placing it in a form, then letting it cool overnight in the new shape. Search youtube for tutorials. Or you can just quench it in cold water and it'll cool nearly immediately. I made some ~35 lb DIY kettl...

Re: Surly Instigator: Steel frame HT + Bafang BBS02 Mid-drive

My rear tire is basically shot and I don't really want to spend $90 on an obscure and nearly obsolete tire size (26+), so I think I'll spend significantly more and convert the bike into a mullet: 29" front, 27.5" rear. If this calculator is accurate, I can run a 130mm 29er fork with minima...

I have some triangle bags and for crash protection I use a carbon fibre plate + closed cell foam. But I am worried if the XC carbon frames can take the dymamic load of a 15-20lbs triangle battery when riding offroad (no hard offroad riding with this bike however) You can probably find some stress m...

I should imagine that minimizing the horizontal seams and reinforcing with webbing might be needed. Horizontal seams and along the zippers are exactly where mine failed (as well as the straps on the 2nd one). 1st was a $10 bag, 2nd was 3-4x that. I got less than 5 miles from bag 1 on moderate singl...

I'm totally with you on the avoidance of mud anymore. I raced my state's enduro circuit for decades and the occasional "mud run" was a nasty requirement. It was hell on equipment, not to mention the rider. MTB's don't fare any better, and let's be honest...it's just not as much fun when y...

If yes, I think a triangle batter...

Re: Battery Triangle Bag - Carbon Frame

As long as you're well below the max rider weight for the bike, I wouldn't worry about it. You might want to consider if you really need a battery that size though. Unless you're doing mega rides of 30-40+ miles or want to ride all the time at max assist, it's a waste.

Re: Does this seem legit?

I'm not very familiar with hub motors but a mid drive with half the power can hit low to mid 30s on a mountain bike. Doesn't seem like too much of a stretch for this to hit ~40 with skinny tires. And speaking of tires note this wheel says it's for "700x28" tires. So you'll need a 29er fram...
