Bicycle Bio

Trying to legally acquire a LimeBike for the museum proved a nearly year-long task. When we found this one in mid-2019, LimeBikes weren’t as common to find on the used market as they are now. Since then, warehouses – especially on the west coast – have cropped up with containers of brand-new Lime-B’s, and even Lime-E’s. (Of course we want one of those Lime-Es, but can’t afford one at $600 a pop. Fill in your preferred GoFundMe joke here).

Still, some ex-deployed bikes do survive, and this one escaped Miami-Dade County’s infamous August 2018 crackdown on dockless providers – in addition to Lime’s eventual scrapping of the local B fleet.

I approached numerous cities to see if any had been removed from the public ROW or seized by subcontracted towing firms, but – apparently – I was a few months late to the party. Trying to get whatever was still out there proved to be quite the task. Eventually, thanks to friends at Miami-Dade Parks, someone remembered a Lime-B that Lime had failed to retrieve and had since become County property.

Days from being thrown in a garbage bin for good, this Lime-B was pushed through the necessary channels to became part of the Museum. I’m told that Parks staff were speechless to learn that anyone had the slightest interest in it.

Enter the battered and beaten carcass of Lime-B #122-949.

At a distance, it appeared to be an intact bike, disfigured only by its severely damaged front basket. But a closer look revealed tire marks on the front rim, and further inspection unearthed that a few spokes had pulled through the rim from the stress. The impact also bent the original handlebar. Our original article about this bike goes into all the gory details.

Somehow, the frame and fork emerged from this abuse straight as an arrow.

I said the frame was straight, right? Well, I didn’t say anything about the bits on the frame. Sure enough, the chainguard mounting tab had been kicked inboard. Not only was it bent, but it was now rubbing against the chain – which had already sawed through most of it.

This is why dockless bikes are overbuilt, folks.

Unlike steel, you just can’t straighten anything with an aluminum frame. Once it’s bent, it stays bent – until it breaks off.

…ah, the joys of JB Weld.

With a washer for reinforcement, the tab – fragile as it is – is back where it belongs. Mint? No. A repair to be proud of? Probably not. Did it ensure preservation of an actual Lime-B? Yes. If it wasn’t for this fix, I’d still be hunting about for another candidate.

But this left just about everything else in need of replacement. I went on an initial whirlwind of parts restoration, sanding off the UV-damaged plastic from the fenders and polishing them out, removing the rust off the stays with oxalic acid, and generally wondering what I’d do about the wrecked rims.

And guess what? Parks eventually dug up another abandoned Lime-B, only this one was nearly mint…if you ignored the fact that vandals had torn the lock plate right off the frame at its welds. An absolute senseless waste.

Nevertheless, it was good news for #122-949. I chose to use a few of the restored parts – including the original stem with matching QR code – but for the most part, transplanted almost everything else from the donor, which was in much better shape.

The donor bike was also a factory 3-speed, which meant #122-949 would get a bit of an upgrade in the process. All the correct parts were on the donor, so it looks as if it came like that in the first place.

The only thing I haven’t been able to sort out is the original lock. The trashed original from #122-949 is the only one I have to work with, and the aluminum shell has been abused quite a bit. These Lime locks are armored well to prevent vandalism, but the lower edge doesn’t hold up, cosmetically:

I’ve shown the lock shell to a few friends who do TIG welding. None of them are convinced they can build up material at the edge, nor do they expect that the weld could be re-shaped thin enough to allow the original rear plate to fit. The lock engagement button is a 3D-printed replica of the original.

I’d hoped to reveal the bike with the original lock restored, but it’s been a major stumbling block, delaying the reveal for months now. Nevertheless, the end result presents well. Who would think that this same bike was abused nearly beyond recognition just a year ago?

But let’s talk about the legacy of the Lime-B for a moment.

Functionally, Lime-Bs are extremely simple bikes. Their band brakes are decent enough (Note that 3 and 8-speed models received a roller brake in the rear), but if they’re not set up just right, they’ll drag and make riding a chore. But that goes for any band brake dockless bike, and ofos are notorious for this.

When set up as a singlespeed, the Lime-B is almost more spartan than most ofos (save for the Shanghai Phoenix), and their gearing is so excessively low as to be left behind in a small-town parade…in 3rd gear.

Seriously, these bikes have 28 tooth chainrings paired with 19t cogs on their Shimano Nexus SG-3R40 3-speed hubs. According to Sheldon Brown’s bicycle gear calculator, that means a Lime-B with a Nexus 3-speed is pushing 26.9, 36.7, and 50 gear inches. Someone must have expected every Lime to go uphill.

The 28 tooth ring is so small that I was able to pair it with a first-generation Sturmey-Archer X-RD8 – a hub geared for 20″ folding bikes – and have perfect gearing. With ISO 559/26″ wheels.

Despite this super low gearing, it is equipped with oodles of fork rake. It makes the front end handling skittish at low speed and difficult to keep in a straight line – and this comes from someone is a stickler for holding a perfect line while riding. Why so much rake for a bike geared to go so slow? Or was it an error that wasn’t caught when the first-generation Lime-B was re-engineered with the smaller ISO 559/26″ wheels?

Who knows?

The fact is, these are not characteristics that make for a share bike with a lasting impression. Far from it. But for what it lacks in substance, the Lime-B makes up in character.

Without question, the Lime-Bs (and first-gen E’s) will forever be remembered as the happiest looking share bikes of all time. The tropical yellow and green livery makes a Lime instantly recognizable from half a mile away and spruces up an otherwise very utilitarian frame.

Even the first-generation B – which sported a black chainguard and BMX-inspired aluminum wheels – has a hard time matching its immediate successor for sheer charisma.

I take it back, This first-gen LimeBike is still the single coolest object in this entire parking lot.

I never understood why Lime scooters didn’t continue the same color scheme. Unfortunately, leaked photos of a prototype, 3rd-generation Lime-E indicates that future bicycles will probably carry the blander, white/green/grey scheme of the scooters.

Fine colors for a website. Not for a dockless bike.

But I’m being a bit hard on the Lime-B. The second generation bike did get some very important details right. Their baskets are deeper and better supported than other dockless bikes. Lime chose to continue using the timelessly perfect North Road handlebar shape, even though it doesn’t help much with the front end geometry. Gen 2 seatposts (with exception to some variants with ofo/Spin style dropper posts) rival the JUMP electric bikes for diameter and strength, and they extend further than dropper posts. To round everything out, Lime’s in-house axle nuts have been such a successful theft deterrent that the design remains in use on their scooters.

Does this make up for the Lime-B’s flaws? You’ll have to decide that. We’ve never experienced the 8-speed version, which probably makes up for a lot of the shortcomings of the single and 3-speed editions.


With that, here’s a photo of one of the last intact Limes to go completely undetected in Miami-Dade County. This is #134-567, which survived “in the jungle” as late as July 2019 – almost a year after being banished from the streets – just off of Sunset Drive at 102nd Avenue. It disappeared a month later.

Foreword and update: When this article was released, the only source we could reach out to was one local Lime employee who explained the scrapping operation in Miami.

Many retired dockless bikes equipped with “dropper” seatposts are now in private hands as daily commuters, but these seatposts are sometimes a bit short.

It was driven over by a truck, and left for dead.
