JUMP charging hubs

Someone asked me recently about the locations of JUMP bike charging hubs in Sacramento. There are 18 on the map below, and one new on on 19th Street just north of Q Street, at the Q19 Apartments development. I captured this map from the JUMP bikes website, which took a little doing.

JUMP bike charging hubs in Sacramento

I recently took photos of all the hubs I could find, and they are part of the Sac bike-share album at https://www.flickr.com/photos/allisondan/albums/72157713653167982. I was able to locate only one of the three hubs shown for Sacramento City College. It may be: 1) I just couldn’t find the other two (they are much harder to see at this time since they don’t have any bright red bikes in them), or 2) they are not charging hubs but regular bike racks, or 3) they are located where construction is going on and are inaccessible or removed. All the rest of them have at least one photo in the album.

So far as I know, there are no charging hubs in Davis, nor in West Sacramento (which shown on the map as part of Sacramento).

When you actually rent a bike, the app shows the location of these hubs, but with no bikes to rent (the system is currently shut down, in case you had not heard), I can’t see what the live map shows. But other than the one new one, I think this map is accurate. Let me know if you know otherwise.

JUMP on Monday, August 6

We counted throughout the day of Monday, August 6, and generated the following data table and gif animation. Monday was not necessarily a typical weekday, as the middle days of the week may be more typical, and it was not a typical use day because the air quality was unhealthy for a portion of the day. The gif animation focuses on Sacramento central city. It is not possible to present much larger areas without losing icon and count detail.


JUMP count update 2018-08-04

There are clearly more bikes on the street now than at last count posting, but I’m not sure how many. The rumor was 100 more bikes in this last week, and 100 more in the week before, but so far I’ve not been able to get anyone to confirm or deny those numbers. If true, that would make a total of 500 bikes in the region. Since the total possible is not known, we can’t say what the availability percentage is. When there were 300 bikes possible, the percentage available ranged up to 56%, but I think that staffing is now catching up with demand and the percentage available may be ranging up to 74%.

I am curious about whether there is an industry standard for the availability of bikes. Since I am pretty sure that JUMP has the vast majority of electric assist bikes in service, and none of the electric bike share systems are very old, I have not been able to find any information. It is worth remembering that electric assist bike share did not even exist in 2016, and the NACTO 2017 bike share report does not mention electric assist bikes at all. This report was released May 2018, so the next report is months away. Of the bike share systems, the only ones with electric assist, so far as I know, are JUMP (dock-optional), Motivate (which operates most of the dock systems in the US), and LimeBike (dockless). I have seen a few Ford GoBike (a Motivate system) electrics in SF, but have not had the opportunity yet to ride one.

There are a number of people returning bikes to the drop zone (green) hubs, either for the 50 cent credit or out of the goodness of their hearts, and I think that is helping keep more bikes out on the streets because it makes it easier for JUMP staff to find and load these for West Sacramento to be charged. It is more likely now that hubs will actually have bikes available because charged bikes are being returned to hubs more frequently.

I was out last night returning low battery bikes to hubs (in between beers), and I saw about 80 bikes in use in various parts of the central city. I also saw ‘in repair’ (low battery) bikes being picked up by JUMP staff at the 17th & R drop zone, at about 10:00 at night, so there is real effort now to keep up with charging.

A caveat about all counts: These counts are done by hand by Dan, and Matt who is now helping, and of course they will not be 100% accurate. In fact, in the time it takes to count the bikes in the app, the numbers have changed, particularly at those times of day when a lot of bikes are in motion, commute hours and going out in the evening hours.

  • Sacramento, 68 bikes out of hub, 18 bikes in hubs, 5 bikes out of service area, total 91 bikes in service.
  • Davis, 37 bikes out of hub, 7 bikes in hubs (2 hubs), 1 bike out of service area, total 45 bikes

  • total 157 bikes

July 20, 7:30AM (picked as a time when recharged bikes may have been distributed, though bikes will be traveling)

  • Sacramento, 63 bikes out of hub, 22 bikes in hubs, 5 bikes out of service area, total 90 bikes

I am not able to compile these kind of statistics on a regular basis, but perhaps we (the users) could pick a few times of day and crowd-source the data.

JUMP hub count

JUMP is gradually adding hubs to the system. As of today, the counts I see are:

  • Davis: 3
  • West Sacramento: 7
  • Sacramento: 60

In Sacramento, the number of hubs exceeds the number of bikes available. at least at certain times of day. The city requirement was two rack spaces, not the JUMP ‘wave’ racks only, but also regular racks, per bike. The hubs have between four and twelve bike spaces, at least the ones I’ve visited. The number of available bikes as of this moment (8:30PM, 2018-07-02) is 51, but I’m sure there are bikes in motion. I saw five bikes being ridden while out on my evening walk.

People have been asking me questions about the bike share system, and pointing out that I have mixed feelings. Yes, that is true. I think it has the power to transform transportation in Sacramento, but is falling short at the moment. I am traveling and backpacking this summer, only occasionally in town, so it probably will not be until mid-August that I’ll have much to say about the system.

Remember, you can always comment on my posts (if you have commented before and been accepted, you comment will automatically get added, if not, I approve, or very rarely disapprove, as soon as I can). If you have written something, you can submit a link to that. Of, if you have more ambition, you can write your own posts for consideration for Getting Around Sacramento. I don’t want my voice to the the only voice.


Bike share is booming

I had a mindset for the last three weeks that the problem with the JUMP system was that bikes were not being used because they were not being charged and re-balanced. But my observations this weekend show that I had things flipped. The system is getting used so much that the bikes are running out of battery. Everywhere I went in the central city, I saw people riding them. I’d see a bike parked, and ten minutes later it was gone, in use by someone else. I don’t know when JUMP will provide rides-per-bike data to the partners, but I think it will indicate that, at least on weekends, each bike is getting many trips per day.

The app map this morning showed almost no bikes in the central city, and what there were were in low-battery status. On my walk, I saw five bikes in very low battery ‘in repair’ status, all within a few blocks of my home. Another had a dead GPS battery, which I think happens when they stay in ‘in repair’ mode for a long time. The bikes are still in the central city, but they are out of juice because they have been used so many times.

Two things users could do to help:

  • If you find a dead GPS battery bike, with the display blank and the keypad unresponsive, email JUMP at support@jumpbikes.com to let them know the location, street and cross-street. Include that it is in Sacramento, or West Sacramento, or Davis, as the bike numbers alone don’t pin down which city the bike is in.
  • If your destination is within a block, or perhaps two, of a hub, park at the hub. That not only makes it easier for the next person to find it, but makes it easier for the JUMP field crew to find it, particularly if it eventually goes to dead battery and drops off the system.

No hub or rack near your destination? You can submit location requests to JUMP at the same support@jumpbikes.com email address. There are a number of locations which have been identified for hubs but not yet installed. Some of them in repurposed parking spaces, marked with thick white lines and two delineators. But it doesn’t hurt to submit an already planned location, so go ahead. SACOG has promised a map of future hub locations, but I’ve not seen it. Presumably it will show up on the SACOG Bike Share page: https://www.sacog.org/bike-share.

a day in the life… of bike share

I saw a cool graphic of the flow of JUMP bike share bikes in San Francisco, and thought is would be interesting to do the same for Sacramento. The effect is not so dramatic, but it is interesting. I have zeroed in on the central city, which of course only tells part of the story, but this is the level at which bike and hub icons show, whereas the next zoom out only shows them as dots. I’d like to do this for a weekday as well, but probably won’t have the chance for several weeks, as I’m out of town.

The first one is Saturday, at a few points in time, the second one is Sunday, at three hour intervals. Maybe like watching paint dry, maybe better.



JUMP SF and Sac bikes

There are at least two San Francisco bikes in Sacramento, and I’ve come across them and ridden them. The most obvious, though subtle, difference is that the SF bikes have eight gears and the Sacramento bikes three, as befits the terrain. The shifting direction is reversed.

Since I rode these bikes on the same day that I rode Sacramento bikes, I could compare them directly, and the feeling I’d had when I’d ridden them several days apart turned out to be accurate. The bikes accelerate the same, but once reaching top speed of 15 mph for Sacramento bikes and 20 mph for San Francisco, the Sacramento bikes drop out of assist roughly, and continue to go in and out of it, surging and bogging down. The San Francisco bikes have a smooth transition, noticeable, but much smoother, going from assist to not in a comfortable manner.

The Sacramento bikes make a lot more noise than the San Francisco bikes. Sometimes people turn their head to look. Though I don’t know for sure, I suspect this is the result of whatever was implemented to limit the Sacramento bikes to 15 mph, which is not their design speed but a limitation imposed by the City of Sacramento. I’m concerned that the bikes may actually be damaged by this. I do know that when mechanical devices make a lot of noise, it is not a good sign.

I continue to believe that the 15 mph limitation was unnecessary and inappropriate.

JUMP Sac bike count, and locking


The count of JUMP bikes showing on the app on the morning of June 9, 6:00AM, is 55 in Sacramento, 8 in West Sacramento, and 20 in Davis, for a total of 93.

On the evening of Monday, June 4, the counts were: Sacramento 69, West Sacramento 21, and Davis 16, for a total of 106.

On the early morning of Saturday, June 2, the counts were: Sacramento 54, West Sacramento 11, Davis 32, for a total of 97.

Though I’m not counting low-battery, in repair bikes, which is much harder to do since they don’t show up on the app map, my impression is that there are many fewer of these out.

Someone from San Francisco created a cool animation that showed the flow of bikes between the financial district and Market Street, during the day, and the outer margins of the service area in the evening. I want to do this for Sacramento, but haven’t had the time yet.


I have found a few bikes improperly locked, but not many. Other people have commented on this, but it doesn’t seem to be a common problem. In the app, under the left menu, Support > How It Works > Locking a Bike, it says that the bike must be locked to a rack (see the full text below). I’ve seen other detail on locking, but can’t track it down at the moment. Bikes do get locked to sign posts and parking meters. Though this is not technically OK, it seems to be accepted so long as the bike is not blocking sidewalk access or ADA access.

My advice is: try to find a rack, or even better, a hub. If you can’t, find something else secure, but think about how other people might need to move around it. Can a person access their car or parking meter? Does it intrude into the sidewalk? Does it keep people from getting to newspaper racks?

Over time, there will be more hubs, installed by JUMP, and more bike racks in general, most installed by the cities, but for now there are many areas of town where there simply aren’t any bike racks, and sign posts and parking meters are the only option.

In case you are wondering, the JUMP-designed racks, which they call wave racks, and had a base and cutout circle for the lock, are required by the City of Sacramento in any location where a bike might intrude into the roadway, as they enforce locking in such as way as it won’t. In other locations where this is not an issue, or where the rack has not yet been replaced, regular bike racks of various sorts are used.

At the station

You can lock a JUMP bike at any hub location free of charge. Simply secure the U-bar around the rack and insert into the designated holes at the rear of the bike. Give it a gentle tug to confirm it’s secure. The keypad LCD interface will confirm that the reservation is complete.

Outside of a station

You can lock a JUMP bike out-fo-hub at a regular bike rack as long as it’s still inside the system area. Simply secure the U-bar around the rack and insert into the designated holes at the rear of the bike. Give it a gentle tug to confirm it’s secure. The keypad LCD interface will confirm that the reservation is complete.

Using the hold feature

Need to grab a coffee on your ride? Not near a hub location? Need to hang onto the bike? You can use the ‘hold’ button on the keypad to keep your reservation running, and lock the bike out-of-hub. You will not be charged the out-of-hub fee. Lock the U-bar around a secure bike rack, and check the keypad to make sure the screen indicates the bike is on hold. Note that your rental is still running during this period.

Using the repair feature

Got a flat tire during your ride? Press the ‘repair’ button on the keypad and secure the U-bar around a rack and lock it into the rear of the bike. Give it a gentle tug to confirm it’s secure. Details about the issue will be send to the operator letting them know your had a problem. The bike will be unavailable until the issue is resolved.

Letter to Ryan Rzepecki

To summarize: Don’t. Please, don’t.

Why? Why not be bought out by Uber? Because the objectives and culture are not a good fit.

JUMP (SoBi) has a model of disruption based on offering a better product, meeting the need of people, and making a profit in the good work. Every SoBi employee I’ve had interactions with had a passion for making the world a better place through bike share. When there were problems, each person I spoke with or emailed made sure to get it right. SoBi works with the cities it goes into, negotiating the terms but wanting to make sure it works for the company, the city, and the users.

Uber is the exact opposite. Their business model of disruption is to break every law they can get away with breaking, to cut every corner. Their intent is to drive every competitor out of business, as they must if they are ever to stop losing money. They treat employees like dirt (yes, the drivers are employees by definition of labor law, though at least in the US Uber is so lawyered up that the federal government and state governments have either not been able to compel Uber to follow the law, or don’t care to. In every city in which it operates, in the US and in Europe, Uber has violated law after law after law.

These two things do not match, and can never match.

One of the great hopes that I have for electric bike share is that it can displace many of the ride hailing trips that exist because it is time competitive with and cost positive over ride hailing in denser urban areas. I see uncontrolled ride hailing as the worst thing that could happen to our cities, and anything that lessens that damage is a great thing. That puts the ideal of bike share in direct conflict with the idea of ride hailing. The terms ‘shared mobility’ and ‘mobility as a service’ are all the rage these days, but I don’t see any mode that uses low occupancy energy guzzling cars (electric just shifts impacts from fossil fuel burning at the car to fossil fuel burning at the power plant, at least so far) as complementing any other mode. They are not a complement, they are a competition.

But the biggest conflict is on the streets. Bike riders, the users of SoBi and JUMP bikes, want more than anything to be safe. But they can’t be safe so long as poorly trained commercial drivers (Uber) terrorize bicyclists by driving over the speed limit, making sudden right and left turns, and looking at smart phones instead of at the road. Uber drivers block bike lanes more often than other ride hailing companies. I’m not sure why, but suspect it has to do with drivers adopting the attitudes of their company.

When I am bicycling in San Francisco (headed there for the weekend right now), I can hardly even use bike lanes on many streets because they are blocked so often by ride hailing. Do they look when pulling in? Do they look when pulling out? Seldom. As a vehicular bicyclist, I know how to deal with this, to just use the general purpose lane and avoid the bike lane, but I assure you, this is not the experience most bicyclists are looking for.

Bicyclists want safety. Uber does not.

I am really concerned that this is the beginning of the end of SoBi/JUMP, and that would make me very sad. Uber may kill off bike share once it realizes that the values and goals of bike share are opposed to their own. Another not unlikely possibility is that Uber will go under, under the weight of endless lawsuits that will sooner or later start to be successful. If you run a criminal enterprise, it will eventually catch up with you, whether you are Uber or the president.

To summarize: Don’t. Please don’t
