Some of our guides contain affiliate links. If you buy through one, we may earn a small commission at no extra cost to you. Here is how that works.
How we put this together: we have not ridden this bike ourselves. What follows is based on Gazelle’s published specifications and on independent reviews, which we link where we use their figures. Where a number is a manufacturer claim rather than a measured result, we say so. Read more about how we research.
The Gazelle Ultimate C380 HMB is a Dutch built commuter and trekking e-bike pairing a Bosch mid drive motor with an Enviolo stepless hub and a Gates carbon belt. Gazelle lists it on its US site at $4,999, which puts it against the most expensive city e-bikes sold in the country.
That price buys a specific kind of bike: quiet, low maintenance, heavily equipped, and built around comfort rather than speed. Several of its weak points are structural rather than fixable. Below is what the published specifications and independent reviews support, and where the evidence runs out.
Who this bike is for
The Ultimate C380 HMB makes most sense for a rider who wants transportation that behaves like an appliance. The belt needs no oiling and will not mark trouser legs. The Enviolo hub has no cassette, no derailleur hanger, and no indexed clicks, so gear changes are smooth and can be made at a standstill. Lights, fenders, rack, kickstand, and a frame lock all come fitted.
It also suits riders who struggle with conventional shifting, since there are no gear numbers to learn. Riders with hand or wrist limitations should note the tradeoff below, and may want to compare it against our guide to the best electric bikes for seniors with arthritis.
It is a poor match for anyone who needs to carry a bike up stairs, keep pace with fast group rides, or ride steep unpaved climbs. For a daily work trip it belongs on the shortlist alongside the options in our roundup of the best electric bikes for commuting.

One caution on the weight. Gazelle quotes 56.4 lbs without the battery, and a Bosch pack this size adds about seven pounds, so what a rider lifts is in the low sixties.
What independent testing found
Coverage is thinner than the price suggests, and much of it describes the earlier version: a 500 Wh battery, a 65 Nm Bosch Performance Line motor, the small Bosch Purion display, and a $3,999 list price.
Electric Bike Review weighed that version at 63.4 lbs including a 6.9 lb battery, and measured 17.5 inches of standover on the medium frame. Its reviewer credited the low standover and the rack, estimated 35 to 90 miles of range depending on assist and terrain, and attributed about four pounds of the weight to the hub itself.
Tom’s Guide also tested the 500 Wh version, praising the smooth power delivery and the four piston brakes at over 30 mph downhill. It ran no range test and listed a maximum estimated range of 43 miles.
Notebookcheck reviewed the European Smart System model with the 75 Nm motor, weighed it at 25.8 kg with pedals, and liked the fine cadence control and braking feel, but found the gearing too long for steep mountain climbs.
One gap matters: no review we found published a controlled range test for this model. Gazelle’s own figures make the point, since the same battery is claimed to give 115 miles in Eco and 47 in Turbo. Real results at high assist land well below the headline number once hills, headwinds, cold, rider weight, and cargo are added. Our explainer on electric bike range covers why claims and lived results diverge.
Where it falls short
Price. At $4,999 it costs roughly double a well specified direct to consumer commuter with a comparable battery. That premium buys the belt, the hub, the frame lock, and the ten year frame warranty rather than raw performance.
Weight. With the battery installed this is a bike in the low sixties in pounds. Fine on flat ground, awkward everywhere else: apartment stairs, car racks with weight limits, and any ride ending on a dead battery.
The twist shifter. The Enviolo hub is adjusted by twisting a grip, and the mechanical version fitted here takes real hand and wrist effort, more than clicking a trigger shifter. Electric Bike Review also noted it shows no numeric gear position, so riders work by feel. Anyone with limited grip strength should try this control before buying.
Display and version confusion. The current model uses the Bosch Kiox 300, a real improvement, but remaining and secondhand stock still carries the old Purion: a small fixed grayscale screen with no USB and no phone connectivity. Confirm the motor, battery, and display before paying.
Frequently asked questions
How far will the Gazelle Ultimate C380 HMB really go on a charge?
Gazelle claims up to 115 miles in Eco and 47 miles in Turbo on the 625 Wh battery. Those are claims, not measured results, and the Eco figure assumes light assist on flat ground. Riders who stay in higher assist levels, carry cargo, or ride hills should plan around the bottom of that spread or below it.
Is it a Class 1 or Class 3 e-bike?
Class 1, with pedal assist to 20 mph and no throttle. The separate Ultimate C380+ uses the faster Bosch Performance Line Speed motor and is a Class 3 bike assisting to 28 mph.
How much maintenance does the belt and hub setup need?
Less than a chain and derailleur. The Gates belt needs no lubrication and does not stretch, and the sealed hub shifts consistently in bad weather. It is not maintenance free: belt tension, brake pads, tires, and periodic hub service still need attention, usually at a dealer. Our electric bicycle maintenance guide covers the routine items.
Is the bike still available in the United States?
Yes. Gazelle lists it at $4,999 in the Smart System specification with the 625 Wh battery. Dealers may still hold older 500 Wh stock at lower prices, so check the configuration on any discounted bike.
The bottom line
The Ultimate C380 HMB is a heavily equipped Dutch commuter with a strong warranty and a drivetrain built to be ignored for years. The published evidence supports the claims about build quality, braking, and quiet power delivery. It does not support treating the headline range figure as a plan.
Buyers who want low upkeep, an upright position, and a bike ready to commute will find value here. Buyers who care about weight, steep climbing, or maximum battery per dollar should look elsewhere. Either way, test the twist shifter and lift the bike with its battery in before committing $4,999.
