Excellent day to be out on the road bike. Started with a short social ride, then spun over to do some volunteer mechanics at the non-profit bike shop and finished by rolling over to catch a college baseball game.
I still really like this modern build of an old Chicago Schwinn. It’s not quite as snappy and sporty as recent frames but very stable and handles well at speed.
Commuted by ebike which was a third test ride of a rebuild. I received the bike with a bad battery which was replaced. Bike was loaned out and seems the controller fried during use. So new controller and display from aliexpress. Frame bag to hold the controller, parts bin throttle, plus motor cable extension and different y-cable to the front. Frankenstein ebike seems to be working alright now.
Pedaled about to run some errands and go to a dentist appointment. It was a nice day so rode out by the river to have a snack. It was glorious.
I had forgotten how refreshing and enjoyable road biking can be.
Tested internal resistance on the collection of 18650 cells and entered all the data. First pack to build is in a Silverfish type case for a 48v folding e-bike. So the pack is 13 series with groups of 5 in parallel for 65 cells in total.
I’ve pulled the selected cells and placed them in the holder for the case. Next step is try to clean the spot welds off the terminals, add insulation rings and rewrap where needed.
Made time this morning to pedal over to the park for a quick loop on the single track. Cooler weather but still looks like spring with tiny green herbaceous plants shooting up from the leaf litter.
Ended up buying another old hard tail after find a cracked head tube on the last one. This one is steel, also a 1999 model year and basically the same geometry. Looked at frames on flea-bay, thinking I’d transfer parts. Checked at the local bike co-op and cost was same as just a frame.
Finished tearing down all the packs I know have Samsung 25R cells inside. Also finished capacity testing the 211 cells that were salvaged.
Next step is checking the internal resistance and voltage after they have sat for some time. Then input capacity and IR data into the pack builder tool on cell saviors website and hopefully build some working ebike battery packs.
Foggy and slightly damp morning ride. Enjoyed some single track in the woods. Excellent beginning to a day.
I overhauled an old full squish mountain bike to try for trail riding. Full suspension always felt like a waste when riding on pavement but I hadn’t rode one on trail. This one has coils front and back which feels pretty plush but heavy. It doesn’t lend itself to standing up and aggressively pedaling but it is very comfy. Willing to give it another spin.
Went to the park to ride some single track and enjoy the warm weather. It was an excellent day to be out and in the woods.
Noticed the local mountain bike club has been doing trail work recently to sure up and improve some features. I have a lot of respect for the folks that organize to build and maintain the local single tracks.
This ride was a test of an old Rock Shox Duke that I serviced. The lower axle to crown actually improved the bike, the front end stayed on the ground.
Some early spring cleaning led to a trash run on the bicycle. Great day to be out riding.
