RH212 update Got the new V5 torquearm today and installation was easy peasy. The old torquearm just wasnt the best on this bike (hoseclamps were not elegant for the dropouts so I carried a spare set and I needed to carry two 11 mm wrenches to get the torquearm off). The new torquearm needs an...

FWIW, this was in the broomfield tech center, on the path/sidewalk that parallels 128. It was on a fun downhill section (I slowed down alot for him). I have encountered him before (the 20ft + leash stick in my mind), most likely faster. I have had several heated encounters in this area...

Yes, I definately learned something....just best to keep on going and dont react to someone yelling profanities at you. I tried to be peaceful and logical and and leave with good karma and he wouldnt have any of it. First he threatened to call the police to which I said, "do it" which he told...

Thanks for sharing the history 👍 RH212 update I decided to install a Erider Torque sensor BB and must say that it completely transformed the bike which totally surprised me. Sure I prefer the feel of torque sensors but the BBSHD cadence sensing feels pretty good (my favorite DIY ebike to...

North of Denver up to Boulder: 8/10 I live north of you in Louisville. Im amazed at what I can ride from my house, everything from the 36 bikeway to all sorts of gravel rides. Dedicated legal eMTB rides do require travel though. (Boulder OSMP is quirky and this is in quite the influx at the...

Update from last post I have given up trying to compare the RH212 to the GMAC and BBSHD for the ride I had outlined(worst case for hub drives). I seem to always do it faster in the BBSHD which makes it hard to compare stats like efficiency. This probably just shows that the BBSHD/mid drive is...

Lemon pledge has been used for MTBs for quite awhile, one step clean and polish.

Definately agree....its also the most fun to ride, not sure why that is..perhaps lowest cg. If it had torque sensing thats all I would own. I have high hopes for the CYC proton I did do a 6 month stint on just the BBSHD (on both DIY ebikes). When I went back to the GMAC with torque sensing...

Here is one using a RH212(DD) with statorade compared to a GMAC 10T(geared hub) https://ebikes.ca/tools/simulator.html?motor=GMAC10T&batt=B5216_GA&wheel=29i&mass=140&axis=mph&motor_b=9C212_7.5T_SA&batt_b=B5216_GA&wheel_b=29i&mass_b=140&bopen=true&grade=9&grade_b=9 The DD starts to overheat over...

I love the silence of my RH212 as well. It definately is a dog below 15mph and starting from a stop. Hills take quite a bit more power (i.e. 0% to 6% I go from a constant 300W to 600W. I can also use my legs). All that matters is that you like it 👍 The hub vs mid-drive debate will never end...

Isnt the grin motor simulator fun. You can also play with I think their trip analyzer and use actual terrain data. Lots of variables to play with (lots of videos on how to use). Justin also gave some good insights to his BBS02/BBSHD testing and incorporation into the tool on...

I would agree with that both from experience and using the grin motor simulator. Sure the geared hub drive can go up steep hills, just not for long. I did an exhausting analysis on the grin simulator a few years back and the GMAC10t would start overheating at anything over 6% (at full power)...

This comparison at grin seems to contradict your claim...

On the subject of butt soreness, I only recently started encountering it in the last few years. All my riding is on flat handlebars. What has changed? I have slowly been raising handlebar height due hand numbness. There can be all sorts of reasons for this (age, weight, core strength). At...

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
