I wanted to tackle the issue of having a seatpost too low. I have two identical setups (Surly Ogres) with every part identical except for the motor type (GMAC vs BBSHD) and suspension seatpost type (Redshift(GMAC) Vs Kinekt(BBSHD)). Lets call GMAC bike1 and BBSHD bike2. I ride pretty much...

Perhaps a free year subscription of strava so it can be PROVEN and compared against others for EBR credibility.

I wouldnt narrow down my selection based on a rim having eyelets. I have had failures similar to what was shown on rims with/without eyelets. The rims that failed were all OEM rims and the failures happened pretty soon (with 2-3k miles). Unless you are spending $$, manufacturers try to cut...

How did your derive the 150kg number? What is the limit for 28spoke wheels. I would love to use a website that showed me this data. Strava?

I think stefan was somehow trying to give credibility to the concept of 'underbiking'. https://www.merlincycles.com/blog/underbiking-whats-the-point/#:~:text=In a nutshell, underbiking is,on a cross country bike. Basically it something roadies (who dont like MTBs) do. Its silly IMHO. Why...

Its really more of a demo of worst case conditions for his ride (throttle only) vs temps. Thats what I got out of it

Good summary here: I use them both and completely agree on his analysis, although he doesnt have a strava account or use his strava account to get credibility. Kinekt is better for the bigger hits, Redshift is better for milder gravel rides. I have them on bikes which match these criteria...

I happen to live in a very fitness/cycling oriented area (near boulder, CO). Ebike usage out here has exploded in the last few years. I would say over 80% of the bikes I see are throttle bikes and probably 50% percent of those I see are using throttle only...until they see you and then...

The last leg of my rides usually end up with a 6 mile section (roughly) of rolling 4-6% hills (long 6% grade at the end) bucking a headwind. I have handlebars that allow me to get into an aero tuck (origin 8 strongbow) and on windy days, I am passing bikes like that. With the wind at 30mph...

When I lived in Dallas, Tx (86-88) we made skateboard longboards(with our windsurfing sails) and rode in parking lots at night when the wind would pick up. Apparent wind was awesome until a gust stopped and the sail would backwind (while your doing 20+mph). Surpised I never hurt myself. High...

Ugghh, 40mph winds today with gusts to 60 just outside of Boulder, CO. My house does this twisting motion with the higher wind gusts High winds encountered during the winter are the main reason I use higher power ebikes I do miss the winds in the SF bay area. I actually moved there in 88 to...

No arguments on the benefits of the BBSHD, so easy to make a clean 36mph capable bike....I love mine. If I could have only 1 DIY bike, it would be equipped with a BBSHD. Yeah, in the scheme of things, I definately spend more on my Grin Stuff but usually dont do it all at once and the high...

Yeah, I added up the cost for my latest BBSHD build $520 Luna Bare Motor $30 stock crankarms (seem to work for me) $90 eggrider display (other displays are close in price) $16 stabilizer bar (Full suspension, I just prefer to use these) $145 Lekkie BlingRing 42t Total $809 Thanks for the link...

Funny you should mention that! This would be a great addition to my acoustic 2019 Santa Cruz Tallboy Carbon (motor wise) acoustic bike. I cant see any DIY battery mounts on the carbon frame that would stand up to the trails it would encounter so it would be a backpack battery (you can stick...

I am considering the photon as well although the last thing I need is another ebike. $850 USD price tag is pretty hard to swallow though especially for the power. My BBSHD is basically perfect for my needs and has stood up to all the abuse I have thrown at it, sure wish it had a torque sensor...

Interestingly on a pack that had a bad cell and required disposal, I disassembled it to individual cells and discharged each one with a small automotive light bulb. How did I know each cell was done?, you could hear the noise of the cell venting when the voltage got low enough

Most likely, the data being shown while sampled at 1Hz(by the app) is sampled at higher frequencies within the embedded firmware within the motor and then averaged according to some criteria (of which I have mentioned previously). That data (before being averaged) is what is considered RAW data...

Its pretty common knowledge in the RC industry that 18650 cells shouldnt be totally discharged in less that 1/2 hour due to their high internal resistance. I have used High Current RC Lipo packs for FPV drone flying and discharged them in a minute...they usually puff and dont work...

Are you actually trying to imply that all sampling in the world occurs at 1Hz. Thats an insane and completely false claim. I have worked in the embedded software industry for well over 35 years including avionics flight controls, measurement, test, simulation and most recently spacecraft...
