e-Bike Hydraulic Brake Swap (The Juiced Gets Juice-Filled Brakes)

-
After two years of hauling my less-than-svelte behind around, the Juiced has earned an upgrade in the stopping department.


[I wasn't planning on writing about this, but Jim from Jim's Obsessive Cycling Disorder asked if I'd share my results from this cheap caliper swap and I figured I'd just share it with everybody. Thanks, Jim!]

See Jim's Brake upgrade here

I've been commuting on the OceanCurrent  for two years now. Other than cable adjustments and switching to thorn-resistant tubes, it's been an impressively maintenance-free bike. But the brake pads are almost gone and I wanted to upgrade to hydraulic brakes before winter sets in.

So I started looking at ready-made hydraulic brake kits like this:


But e-bike brake levers have a built-in electric switch that acts as a motor cutout when you apply the brakes, so the set pictured above won't do the trick. I had to find another solution or pay a much higher price for an e-bike specific set of brakes.



A little bit of googling presented another solution - cable-actuated hydraulic calipers. I ordered a pair of these for about $40.

The Zoom Xtech HB-100

Before I did the swap, I made four before runs. From 15mph to a full stop, I averaged 26 feet. Not bad for 300 pounds of bike and rider. (Did I mention that my bike weighs 200 pounds? ;-)


The swap was really easy and took considerably less time than it's taking me to write this post - less than ten minutes per caliper.


Removal consisted of taking the brake cable loose and removing two allen-headed bolts. Installation was the reversal of that with a few seconds thrown in for centering the caliper. (Yes, Jim, you did it the right way - I should've made a video too. Maybe next time.)

The brakes instantly felt smoother and stronger. When I started the distance tests, I had to adapt a bit because it was very easy to lock the brakes up - which was never an issue before. So I shifted  my weight to the back tire as much as possible and did four runs with an average of 17 feet. (Each run left a black stripe on the road.)

Yes, I am impressed with the performance. Will they hold up for the long run? I hope so, and I'll let you know.


For now, I'm excited about the upgrade and have to say - I do not get tired of riding this great machine.

May you continue to enjoy the ride and may it keep getting better.

As always, thanks for reading!

Finally - tackling the No-Weld, Longtail DIY Cargo Bike (for hopefully less than $100)

I finally started, y'all! Long-time readers of MH or 2WM are thinking, Jeez, MH, it took you long enough! To that I say,  Both of you are absolutely right. Our biggest-ever posts on both blogs have been about cargo bikes, and the really big one is about a No-Weld DIY Longtail Cargo Bike . So, here we go, people - it's time to build one. This week, the final piece fell into place: a Giant Simple Single cruiser bike ($35ish). Originally, I planned to pick up a cheap Huffy cruiser for the build, but cheap Huffys (Huffies?) have been rather rare lately, so I ended up with a nicer (but cheaper) bike. The free swingarm donor The other two main components that previously came into place are a nice and very cheap 3-speed Schwinn step-through ($20 and not pictured) and a junky full-suspension mountain bike ($0). So, the goal here is to balance this equation: Giant + Schwinn + Junky MTB = Longtail Cargo Bike < $100 Humble beginnings (I'll also

New Turn-Key Klunkers (Or DIY your own)

Yep, my most recent distractions have been variations on the klunker. I've always been fond of upcycled vehicles, the ones where you take something old and uncared-for and turn it into something useful and enjoyed. Cafe racers, resto-mods, rat rods, lowriders, bobbers, all of them have caught my eye over the years. And the klunker fits right in. About forty years ago, some people in California started using old balloon-tired cruiser bicycles and modifying them to become the prototype for the modern mountain bike. If you do an image search for a klunker, you get something that looks like this: That's a whole lot of DIY retro-coolness! But wait.... Yep, at least eight of those are not DIY - they are new! Sure enough, for those of you with klunker lust who'd rather ride than wrench, there are options out there, and some are relatively affordable. The Retrospec Sully For a little over $300 you can have a well equipped klunker with retro looks and qu

A Return to Low $ Turn-Key Klunkers (Under $500)

So, let's talk turn-key klunker again. After spending a year riding and upgrading a (pseudo) klunker, it's become my favorite type of bike. The old HuffKlunk morphed into my favorite mountain-BMX-short-distance commuter, and it's the easiest bike for a grab-and-go ride. Surprisingly, it's also one of the lightest and most comfortable bikes I've owned. So, now I keep an eye out for klunker news and...guess what - a new one popped up this week - the Schwinn Rumbler. And it's down in my almost-willing-to-spend-that-on-a-bike price range. Schwinn Rumbler (at City Grounds) The few specs I found Schwinn Rumbler (Blue) While the thing is gorgeous, I have one concern - it looks pretty small. (My legs like bigger bikes.) I can only find it on the City Grounds site and on eBay (where it costs a lot more). There are no photos of it next to anything for reference. It's not even listed on the Schwinn website. But I love the look and the BMX components and retro straight-
