The AIMA Big Sur Sport 2.0 combines a step-through aluminum frame, 20x4-inch fat tires and a 750W Bafang rear-hub motor. Its removable 48V 20Ah battery provides a calculated 960Wh capacity. Tampa Bay eBikes lists the Sage Green model at $2,099 as of October 16, 2026; pricing and availability can change.
This buying guide covers fit, battery specifications, selectable pedal-sensing modes and components. Use it to narrow your choice, then confirm the delivered configuration and individual fit with the shop.
Frame Sizing, Geometry, and Storage Clearances
The Big Sur Sport 2.0 utilizes a 6061 single-butted aluminum alloy step-through frame engineered for simple mounting and dismounting. Official manufacturer specifications list a standover height of 16.81 inches, a minimum saddle height of 31.18 inches, and a total overall length of 69.69 inches. While the manufacturer recommends this single-size frame for riders between 5'0" and 6'3", this height bracket serves strictly as an initial guideline rather than a definitive fit.
Check comfortable mounting, handlebar reach and appropriate leg extension while pedaling. Practice stopping and placing a foot securely on the ground. A rider-height range is a starting point, not a guarantee of fit.
 |
The step-through design provides a low 16.81-inch standover clearance for straightforward mounting.
AIMA lists a weight of 77.2 pounds, and the frame does not fold. Consider the effort of lifting it into a vehicle or carrying it upstairs. Measure storage access against its 69.69-inch overall length, and verify any vehicle carrier’s per-bike weight limit, tire-width fit and wheelbase compatibility.
The published 400-pound payload capacity represents the maximum gross weight of the rider, riding gear, and mounted cargo combined. It does not indicate the carrying rating for the rear frame structure or authorize carrying a second adult passenger.
Motor Drive, Dual-Sensor Modes, and Display Technology
The 750W Bafang rear-hub motor offers five pedal-assist levels and selectable torque or cadence sensing. Torque sensing responds to pedal pressure; cadence sensing responds to pedal rotation. Ask the shop to demonstrate both modes so you can compare their feel.
The Shimano 7-speed drivetrain has a 52T chainring and an 11–28T cassette. AIMA lists a C010 Bafang TFT color display and Apple Find My support. Check compatible setup requirements with the shop.
 |
A 52T chainring and Shimano 7-speed drivetrain provide standard mechanical gearing alongside the hub motor.
Published speed figures differ: AIMA lists 20 mph, while the shop lists approximately 20 mph on throttle and 28 mph with pedal assist. Confirm the delivered configuration with Tampa Bay eBikes before purchasing.
Apple Find My support can help with location tracking, but it does not replace a physical lock and secure storage.
Battery Specs and Real-World Range Expectations
AIMA specifies a removable 48V 20Ah battery with LG cells. The listed voltage multiplied by amp-hour capacity gives 960Wh. Ask the shop to demonstrate removal and refitting, and follow the supplied charging and storage instructions.
AIMA advertises up to 80 miles, while Tampa Bay eBikes lists an estimated 40–75+ miles. These are published estimates, not mileage measured in a Tampa Bay eBikes road test or a promise for your ride.
 |
The removable 48V 20Ah battery provides 960 watt-hours of capacity for commuting and utility travel.
Everyday battery range fluctuates significantly based on practical operating factors:
- Total payload weight, including the rider, heavy backpacks, and cargo accessories.
- Headwinds, ambient air temperature, and hilly or uneven road surfaces.
- Selected assist levels, frequent throttle use, and rapid stop-and-go acceleration patterns.
- Tire pressure maintenance across the wide four-inch tire footprint.
For longer rides, plan a battery reserve rather than relying on the upper end of a published estimate.
Suspension, Braking Hardware, and Integrated Lighting
The Zoom front suspension fork includes lockout, and the shop lists 80mm of travel. This is a front-suspension bike with a rigid rear frame and no rear shock. Ask the shop to demonstrate the fork settings.
Tektro hydraulic disc brakes are paired with 203mm rotors. Check lever reach and braking operation during a fit check, and follow the supplied setup and maintenance guidance.
 |
Tektro hydraulic disc brakes paired with 203mm rotors provide controlled stopping power for heavier payloads.
The bike uses 20x4-inch fat tires. Listed equipment includes a headlight, taillight, integrated rear turn signals and a horn. Tire size alone does not establish suitability or permission for a particular path or trail.
Avoid standing water and saltwater exposure, and follow the manufacturer’s cleaning and maintenance instructions.

Frequently Asked Questions
What height range does the AIMA Big Sur Sport 2.0 fit?
The listed range is 5'0" to 6'3". Check comfortable mounting, handlebar reach, pedaling leg extension and secure foot placement at stops. Individual proportions matter beyond overall height.
How much range can a buyer expect?
Published estimates cite up to 80 miles from the manufacturer and 40 to 75+ miles from retail documentation. Practical mileage depends directly on payload weight, assist levels, wind resistance, tire pressure, and riding terrain.
What is the difference between the listed speed figures?
Manufacturer specifications list a standard assisted speed of 20 mph, while store listings state approximately 20 mph on throttle and up to 28 mph on pedal assist. Buyers should verify the exact delivered assist programming directly with the shop.
Does the 400lb total payload mean it can carry a passenger or a heavy rear rack load?
No, the 400-pound payload rating represents the total combined gross weight of the rider, riding gear, and mounted cargo across the entire bicycle. It does not indicate individual rear rack strength or authorize carrying an extra passenger.
What should a buyer confirm before purchasing or arranging a test ride?
Buyers should confirm home storage clearance, vehicle transport rack weight ratings, delivered speed configurations, and showroom floor inventory. Contact the shop ahead of time to verify on-site model and color availability.
