Frame and Size Options

The Velotric Tempo is available in two frame styles: a high-step and a mid-step, each offered in both regular and large sizes. The high-step frame fits riders from 5’1″ to 6’5″ and comes in Lightning Silver and Forest Evergreen colors. The mid-step frame fits riders from 4’10” to 5’11” and is available in Sunset Tangerine and Forest Green.

Motor and Battery

Powered by a 36V 350W rear hub motor, the Tempo reaches a peak power output of 650 watts and delivers 45 Nm of torque. It features an 8-speed transmission with an 11×24 freewheel, a 46-tooth narrow-wide chainring, and an Asera derailleur paired with an 8-speed trigger shifter. The battery is integrated into the down tube—a 36V, 10.14 amp-hour lithium-ion pack providing 374 watt-hours of energy. Charging takes approximately 5 hours with the included 2 amp charger, and the battery can be charged on or off the bike.

Weight and Load Capacity

The bike weighs 39 lbs and supports a maximum payload capacity of 330 lbs, making it suitable for a wide range of riders and cargo.

Certifications and Durability

The Velotric Tempo carries UL2271 and UL2849 safety certifications and boasts an IPX7 waterproof rating for the battery (protected up to 3 meters for 30 minutes) and an IPX6 rating for the bike itself, ensuring resistance to high-pressure water streams from any angle.

Pedal Assist and Throttle Modes

As a class 2 eBike, the Tempo can reach speeds of up to 20 mph using the thumb throttle or pedal assist. Riders can unlock class 3 speeds for pedal assist up to 28 mph, though throttle is disabled in this mode. The bike features four levels of pedal assist and allows switching between torque and cadence sensors for different riding styles.

• Torque Mode: Power output depends on the force applied to the pedals, providing a natural riding experience. Higher pedal pressure results in increased motor assistance.
• Cadence Mode: Maintains a steady speed as long as the rider pedals, regardless of pedal pressure.

Throttle response and pedal assist can be fine-tuned with settings ranging from smooth to turbo, adjustable both on the bike’s display and via the Velre app.

Pulse Mode: Heart Rate–Based Assistance

One of the most innovative features of the Velotric Tempo is its pulse mode, which uses a heart rate monitor to regulate motor assistance. By setting target heart rate zones based on rider data (age, height, weight), the eBike automatically adjusts power output to keep the rider within desired cardiovascular zones. This mode enhances fitness training by either increasing or decreasing motor support to maintain a consistent heart rate zone.

Ride Comfort and Adjustability

The Tempo comes with a quick-release seat post and a medium-wide seat equipped with shock absorbers. Although the bike itself is rigid without built-in suspension, the reviewer recommends adding a suspension seat post for enhanced comfort, especially on rough terrain. The adjustable stem and handlebar position further improve rider ergonomics.

Tires and Braking

Equipped with 700C x 42C Kenda tan-wall tires featuring a puncture-resistant street tread, the Tempo offers reliable grip on urban roads. Stopping power is provided by Tektro two-piston hydraulic brakes with 180 mm rotors, delivering controlled and confident braking at both 20 mph and 28 mph speeds.

Display and Control Pad

The full-color display features battery percentage, speed, pedal assist levels, class mode, and torque/cadence mode indicators. A control pad on the left handlebar includes:

• Power button
• Up/down buttons for pedal assist adjustment
• Mode button for cycling through submenus
• Left/right turn signal buttons
• Back button for toggling class modes

Additional features include a hidden USB-C port for charging devices and audio feedback for turn signals, which can be disabled if preferred.

Turn Signals and Lighting

The Tempo integrates bright front and dual rear LED lights, brake lights, and turn signals. The headlight outputs 500 lumens, sufficient for daytime and nighttime visibility, and all lights comply with the IPX6 waterproof rating.

Additional Features

• Quick-release seat post for easy adjustment
• Two bottle cage mounts
• Optional plastic fenders and a rear rack with a 66 lb capacity and MC HD system
• NFC security cards for locking and unlocking the bike, adding an extra layer of anti-theft protection

App Integration and Advanced Settings

The Velotric app extends the customization and monitoring capabilities of the Tempo, allowing riders to:

• Name their bike and adjust display preferences
• Toggle riding modes and pulse mode remotely
• Switch between torque and cadence sensor modes
• Adjust throttle synchronization per pedal assist level
• Manage NFC cards and firmware updates
• Track rides with automatic GPS logging and detailed statistics
• Monitor heart rate via compatible trackers, including Garmin devices and Apple Watch integration (pending user setup)

Advanced settings accessible via the app or bike display include speed limit adjustments for each class mode, sensor calibration, ride tuning (adjusting torque and assist percentages), cruise control activation, and auto power-off timing.

Ride Feel and Handling

The reviewer notes that the Velotric Tempo rides closely to an analog bike due to its lightweight frame and responsive motor. The bike is nimble, making it ideal for urban commuting and fitness riding. The lack of suspension requires riders to consider upgrading the seat post for rougher terrain.

Speed Accuracy

GPS speed measurements closely matched the display readings, with minor variances (e.g., 16.9 mph GPS vs. 17 mph display), confirming the accuracy of the onboard system.

Hill Climbing Performance

While throttle-only power is insufficient for steep inclines (tested on a 20-degree hill), pedaling combined with pedal assist enables riders to climb moderate hills effectively. The bike performed better in class 3 mode with pedal assist only, as expected for a fitness-oriented eBike.

Battery Range and Endurance

The reviewer achieved a total ride distance of 23 miles with pedal assist before the battery assist cut out at 22 miles, after which the bike continued as a regular bicycle. This range aligns with the manufacturer’s claims of approximately 40 miles on throttle and 60 miles in low pedal assist. The reviewer notes that riding in pulse mode or higher assist levels reduces battery life notably.

Sand and Off-Road Capability

The Tempo is not designed for sand or loose terrain, as demonstrated by a sand test where the bike could only travel approximately 20 feet before traction was lost. However, its puncture-resistant tires and adjustability make it suitable for paved and light off-road surfaces.

Braking Test

At speeds of 20 mph and 28 mph, the Tektro hydraulic brakes provided strong, stable stopping power with no skidding, leaving visible skid marks and instilling rider confidence.

Walk Mode

The walk assist feature allows the bike to move slowly at roughly 1.9 to 2.2 mph, useful for navigating hills or crowded areas on foot.
