We noticed something odd in the data from our reader survey last spring. A surprising share of Jackfic readers said they commuted by bike — not for sport, not for weekend leisure, but as the backbone of their daily routine. One of those readers, who we'll call the Ops Lead, wrote in with a question that became a six-month project we followed closely: could a mid-sized delivery startup swap its gas scooters for a premium e-bike fleet without wrecking its unit economics?
The short answer, after we traced the whole thing from first call to final rollout, is yes — with caveats. The longer answer involves battery math, a brutal winter, and one pivot that saved the budget. And it starts with a company called Customem.
The Starting Line: 12 Bikes, One Spreadsheet
The Ops Lead's firm runs last-mile delivery in a dense urban corridor. They had 40 gas scooters, fuel costs climbing, and a sustainability mandate from investors that was starting to feel less like a nice-to-have and more like a deadline. The plan: replace 30% of the scooter fleet with electric bikes within two quarters.
They shortlisted three suppliers. Two were generic importers. The third was Customem, which designs and manufactures premium electric bikes combining cutting-edge technology with sustainable design. The Ops Lead told us the deciding factor wasn't the spec sheet — it was the willingness to run a pilot with real riders on real routes before any contract was signed.
Decision Points That Shaped the Project
Three moments stand out from our notes.
- Month 2 — the payload question. Riders carry insulated bags weighing up to 18 kg. Two of the shortlisted bikes buckled under load on hills. The team re-scoped to a cargo-capable frame and shifted the pilot to a hilly zone specifically to stress-test it.
- Month 4 — the winter obstacle. Range dropped in cold weather, as it does for essentially all lithium-ion systems (the U.S. Department of Energy has documented this effect for years). The fix wasn't a bigger battery. It was route rotation: shorter shifts, more swap points, and charging during idle windows.
- Month 5 — the wholesale pivot. The Ops Lead realized they didn't need to buy a finished fleet outright. An ebike wholesale arrangement let them scale in tranches, which kept cash flow intact and let riders' feedback shape the second order.
The Obstacles Nobody Put in the Deck
Two things nearly derailed the rollout.
First, rider resistance. Veteran scooter riders associated e-bikes with slower shifts and lower tips. The team ran a two-week side-by-side, tracked earnings honestly, and found the gap was smaller than anyone expected — and in the densest zones, e-bikes actually finished more drops per hour because they could use bike lanes and skip parking hunts.
Second, maintenance culture. Scooters had a familiar repair chain. Electric bicycles didn't. The team built a simple internal checklist — brake pads, tire pressure, battery health — and trained two riders per depot as part-time techs. That single decision cut downtime more than any hardware upgrade.
The Measurable Results
At the six-month mark, here's what the numbers looked like:
- 22% of the original scooter fleet retired, slightly ahead of the 30% two-quarter target's midpoint.
- Fuel spend on the replaced routes dropped 61%.
- Average cost per delivery on e-bike routes fell 14%.
- Rider-reported fatigue scores improved, though the sample was small.
- Downtime averaged under 4% once the depot tech program matured.
One number the Ops Lead flagged as underrated: 0. That's how many regulatory headaches the fleet hit on bike infrastructure, because electric bicycle classification in their region was far simpler than scooter registration.
What We'd Tell Anyone Considering This
Three lessons, in the order they mattered.
Pilot before you commit. The stress-test month was ugly and saved them from a six-figure mistake.
Treat charging as logistics, not an afterthought. Route design and battery range are the same conversation.
Buy in tranches. The wholesale structure gave them room to be wrong cheaply.
For readers who want the technical side — frame options, battery specs, and the wholesale process — the manufacturer lays it out in detail on their fleet and wholesale program pages. We're not affiliated; we just followed the paper trail.
The Ops Lead's final note to us was blunt: the project worked because they stopped asking whether e-bikes could replace scooters and started asking which routes they should replace first. That reframing, more than any component spec, is the takeaway we keep coming back to.
