Finally assembled and tuned my bike

[Limeybastard]

Got the bike delivered last Tuesday and took my time assembling and checking and double checking whilst studying and researching how components work - still much to learn plus safety first . I am still yet to ride my bike though LOL. All I need now is a swept back handlebar.

It looks great. You definitely need to take it for a spin. Everyone has different tastes on handlebars. I have the Jones Loop bar that has a slight rise to it (SG 2.5) on one of my bikes that I like a lot.

Do you have any pics ?

Not of the completed bike. Here is one during the build. The bars are available in black also.

is that a GMAC?

It is. I didn't want a clutchless motor, but I liked the idea of the integrated torque arm and 10mm axle (so I wouldn't have to file the dropouts). I asked Grin about adding a clutch when they first came out and Justin offered me one of the prototypes that had a clutch.

 

[RunForTheHills]

oh nice.

What battery and controller will you be using?

Phaserunner with a CA3. The battery is a Jumbo Shark 14s5p from EM3EV. I bought these a couple of years ago. I think they are offering the Baserunner with the kit now.

 

[RunForTheHills]

ah okay I see, cool.

yeah I was wondering if you're going with Grin 72V (which probably is a bit overkill) and whether you went with the baserunner of phaserunner.
The Baserunner will give you cleaner look but it's not as good as Phaserunner performance wise so I was just wondering.

72V would be overkill for sure. I don't ride fast at all and the bike has no suspension.

Looking really nice. Thanks.

Quick question if I may, when in gears 1 or 2 and maybe 3 a little, the bike being upside down and me spinning the crank by hand while indexing and checking limits and such. I noticed in the above gears ( 2-3 largest cogs ) the main chainring gets noisy. Initially I thought it was the crank case area, but spinning the crank with no chain is almost silent.

What would cause the chain ring to be noisy when in the largest cogs?

 

[RunForTheHills]

It is hard to tell without looking at it, but I would guess that it is the chainline. The chainring will line up closest with one of the cogs in the back and when in that gear the chain will be in the same plane as the chainring and the rear cog. When in other gears the chain will be at an angle and there will be some rubbing/noise. Since on an electric bike you more likely to use the higher gears, the manufacturer may have optimized the chainline for those gears and the chain is at an angle for the lower gears. It is probably nothing to be concerned about. However, the chainline can be adjusted by changing the bottom bracket to a narrower one to bring the chainring closer to the lower gears (assuming that you don't have a mid-drive motor and that it doesn't cause the chainring to rub on the chainstay).

On the topic of chainline on the Ride1Up 700:

Ride1Up 700 Series Chain Falling Off Front Chain Ring

I have a Ride1Up Step through bike and the chain falls off the front chain ring especially when I hit slight bumps. Has anyone else had this issue? I brought the bike to my local bike shop after Ride1Up support told me to remove a couple chain links. The bike shop looked over the bike and...

Those posts are from over a year ago, I’m hoping my chain won’t fall off from the chainring when I start riding mine as it’s currently noisy as mentioned in larger cogs. Its sounds like the attached pic.
my chainring is noisy on the the largest cogs . Probably means chain will fall off?

If the angle is acute enough, it might fall off the chainring to the inside. That is how a derailleur works. Do you have enough clearance on the chainstay to install a narrower bottom bracket? Bottom brackets aren't expensive, but you do need some special tools to install it or you have to have your LBS install it. The tools aren't too expensive and they are worth having if you are going to work on your own bikes.

Another possibility is to install a chain guide.

MTA: It seems the bottom bracket has an integrated cadence sensor. You might need to go the chain guide route. It is possible that the cadence sensor is separate from the bottom bracket and you can reuse it with a different bottom bracket. Or you may be able to get a compatible cadence sensor from someplace like Grin (ebikes.ca).

I´ve got a pair of North Road bars you could have, but they´re in WA. Just ride the dam thing.

In all fairness I can use the following excuse perhaps. Was waiting on the wife’s e-bike to be delivered , which occurred today.

I could take some pics later. I’m currently in the process of assembling the wife’s ebike and reviewing each step of my work as I go two to three times. I don’t want to be sued by her. tools wise , I am already starting to build a collection of bicycle tools. So it’ll be good

 

[RunForTheHills]

Buy a pack of latex or nitrile gloves and put a couple of them in your bag with the rest of your tools you take on the bike with you. That way if the chain falls off, you won't get greasy putting it back on. I use a small saddle bag for my tools and spare tube. Alternatively, you could pack some alcohol wipes.

Such a ´collection´ tends to accumulate over time. You could wade through mine + assorted bike debris.

No they are not over a year old. The thread was started late summer 2020 and has had posts as recent as April 24th of this year. I recommend reading it. It has some solutions if you run into the problem, but...

Don't worry about something that hasn't happened, yet. How often have you seen someone report their 700's chain falling off in the Ride1Up group? I've seen only one person start a thread complaining about it this year, and he said his was falling off the right side of the chainring and that he was riding in one of the higher gears. I linked to it here:

Ride1Up 700 Series Chain Falling Off Front Chain Ring

Donald Penn, thank you for this information. V helpful in (hopefully) nipping this problem in the bud. I’m about to swing by Home Depot/Lowe’s to pick up those 5 washers before my 700 arrives so that the bike mechanic can install them (in lieu of what R1U sends) when he assembles the bike...

I've only got about 250 miles on my new 700 and have only dropped below 3rd gear one time. My chain hasn't fallen off, yet. If you're riding really bumpy surfaces, you're more likely to have the problem. I ride mostly rural roads. I can avoid most of the big bumps.

Edited to add: On my recently purchased 700 XR, I checked, and it looks like there's less than 1/4" of clearance between the chainring and its closest point point to the chainstay. That doesn't seem like much room to work with for the chainline, although someone in the other thread said a millimeters adjustment made all the difference. I'm not going to worry about it myself unless I start experiencing the issue.

You’re right about that part. Worrying for no reason. We’ll deal with that when we cross that bridge? Or something that effect

We rode today around the cul de sac seemed good. ( first ride on the 700) Will be going for another when the damn FL sun goes down.
In regards to the chainring post and concern. I noticed my wife’s Rad also made that noise on the chainring when her chain was on the largest 2 sprockets.
