Oh man... Sorry to hear! It's going to be one day at a time for a while.

Re: StefEbike for my wonderful disabled wife

They are $20 brakes after all. Frankly, you are lucky that they don't fall off of the bike. :lol: I have no conical washers on the Shimano brakes that I have. My rotors center up fine. That said, only one pad moves and the brakes do rely on rotor flexing as well. But when set up correctly, they don...

Re: StefEbike for my wonderful disabled wife

There's a good sized puncture right in the center of the tube. As usual, I can't find any evidence in the tire. Guess it's not a pinch flat, and it's an easy repair without even removing the wheel. With the 26" front tire, I now have to wait for this tire to wear down, then replace it with the old f...

Re: StefEbike for my wonderful disabled wife

Indeed, at least it was a short walk of shame! When I bought this bike many moons ago, I figured the 700c tires must be fast. Not only was it always more friction than my wife's 26" bike, and like you say the margins were thin for bumps. I pulled the lower chain tube forward a few inches, because it...

Re: StefEbike for my wonderful disabled wife

Aaaand my 700x38C rear tire went flat one mile from home. I'm wishing I had been more brave with my tire selection, and tried to fit 700x45C or even a 622x50 ETRTO. Pretty sure I felt the rim hit on what must have been some rough asphalt on the shoulder, even though I didn't see any hazzards.

Re: StefEbike for my wonderful disabled wife

I'm on a suspension kick this weekend! I didn't originally plan to use this fork since it's 26" and not 700c, but it looked nice and the price was ok, so try it and see what happens. The ride to work this morning was much smoother! The shock has so little friction, you can feel it bounce as you peda...

Re: 60 volt vs 72 volt

Also, today was my first real ride with my new front wheel/suspension setup. It's possible, my old front hub which the bearings feel crummy on was causing measurable drag, lol!

Re: 60 volt vs 72 volt

I'm pretty much just hoping the ebikeling motor has a similar efficiency to the leaf motor, since they appear similar on the inside. I only monitor voltage and amperage through the smart BMS. I need to do as Neptronix suggested, and make a table of wattage for each bike at 10mph increments. The diff...

Re: 60 volt vs 72 volt

I would not bet on any differences in motor efficiency helping your range significantly, and I would bet your motor has comparable efficiency already. My bike and my wife's bike have the same 52v 21ah battery. Her controller pulls 26 amps, and the motor is 25mm wide 0.35mm laminations, I believe a 5...

Sounds like mystery cells used in the battery packs :)

I wouldn't worry too much about the variation shown in voltage readings between the packs.

Re: Frey FAT 1000 2.0 first impressions

My original plan was just to go to 60 volts, since I'm really happy with my bike's performance when the battery is fully charged and for the first 10 miles of battery. After that, the sag makes it less peppy on acceleration or hill climbing. I'd say you should first confirm whether it's less peppy ...

I have two of those exact units working great for the last year. Buy one of the PC adapters as well, to access a few settings that aren't available in the bluetooth app, such as temperature limits.

You're so lucky to have a store like that to try things out. My entire state doesn't have one. I bought my recumbent based on internet reviews :shock:.

Re: PWD's Rocky Mountain Element - refresh

Beefy! I just just looking at 20" tires for my newest experiment, and the Big Ben Plus was one of them... I have a lot of crushed limestone gravel trails around me, and there are sometimes deep sandy sections that throw me off balance.

Re: High performance & durability Cannondale Semi Recumbent

UPS appears to have lost the Bike E. How you lose a 51lbs package is beyond me. Now they're doing an investigation and such. :roll: Reminds me of when UPS lost a $10,000 engine for Rob Dahm, and he found it for sale on ebay. https://jalopnik.com/how-ups-screwed-a-popular-youtube-car-guy-out-of-10-0...

I should have been running the tire pressure higher... Embarrassingly, I haven't found where I placed the CO2 inflator that I got for Christmas, for my intended repair on board kit.

I did ride a few more times to work (20 miles each way), and felt the need to try out my wife's StefEbike for the trip. Even though it's too small of a bike for me, it's a nicer experience, lol!

Re: BMS vs controller vs overload vs noob. Fight!

You and Flat Tire are both saying the same thing. The BMS will cut power temporarily if too much current is drawn from the battery. I greatly prefer a smart BMS to verify that the voltages of each cell group is behaving. Might as well go straight for the 60 amp version , as these are programmable as...

Re: How much can a motor draw?

I agree that it sounds normal. Also power usage monitored between the battery and motor controller includes whatever inefficiencies are lost as heat out of the controller.

Re: High performance & durability Cannondale Semi Recumbent

There are some large chainrings that still have guards, but they're pretty pricey. I like the compactness of the Schlumpf, but I'd also like to try a torque sensing bottom bracket someday.
