The 7-Speed Internal Gear Hub
The Tern Node D7i’s 7-speed Shimano Nexus internal gear hub is a standout feature. Unlike traditional derailleur systems, it’s enclosed within the rear hub, protecting it from the elements and reducing maintenance. It offers a wide gear range suitable for various terrains, making it versatile for city commuting.
Andros Stem
The Andros stem is a unique feature that allows for quick and tool-free adjustments to handlebar height and angle. This is particularly beneficial for riders of different heights or those who prefer to change their riding position frequently.
Folding Mechanism
Tern’s folding mechanism is renowned for its speed and ease of use. The Node D7i can be folded in just 10 seconds, making it convenient for public transport, storage, or car travel.
Schwalbe Big Apple Tires
These tires are designed for comfort and puncture resistance. Their larger volume provides a smoother ride over rough city streets, while the Kevlar reinforcement helps protect against flats. Â
Integrated Lighting Syste
The self-powered lighting system, generated by the front hub dynamo, is a safety feature that eliminates the need for batteries. This ensures you’re always visible in low-light conditions.
Tern Node D7i vs. Brompton Electric
| Feature | Tern Node D7i | Brompton Electric |
|---|---|---|
| Type | Folding bike | Folding electric bike |
| Gear System | 7-speed internal hub | Single-speed with electric assist |
| Frame Material | Aluminum | Steel |
| Weight | 31 lbs. 3.2 oz. | Approximately 35 lbs. (varies by model) |
| Fold Size | Relatively compact | Extremely compact |
| Ride Position | Upright and comfortable | Slightly more forward-leaning |
| Price | Mid-range | Premium |
Comparison
The Tern Node D7i offers a comfortable riding experience with multiple gears, making it suitable for various terrains. Its folding size is practical for most urban environments. However, it lacks electric assist, which can be beneficial for hilly areas or longer commutes. Â
The Brompton Electric prioritizes extreme portability, with a smaller folded size than the Node D7i. It also offers electric assist for added convenience. However, the single-speed gearing and slightly more forward-leaning riding position might not suit everyone’s preferences.
Ultimately, the best choice depends on your specific needs. If you prioritize comfort, multiple gears, and a slightly larger folding size, the Tern Node D7i might be a better option. If extreme portability and electric assist are essential, the Brompton Electric could be the way to go.
Should You Buy the Tern Node D7i?
The Tern Node D7i offers a compelling package for urban commuters, combining comfort, practicality, and portability. However, the design flaws related to the handlepost latch, finish quality, and lack of seatpost markings are disappointing, especially considering the bike’s price point. While the core concept is strong, these issues prevent the Node D7i from reaching its full potential. Â
If you’re considering the Tern Node D7i, it’s worth exploring these alternatives
- Brompton Electric: Known for its compact fold and electric assist, the Brompton offers a premium folding bike experience. Â
- Dahon Mu P8: A more budget-friendly option with a similar folding mechanism and comfortable riding position.
Ultimately, the Tern Node D7i is a capable folding bike with potential, but the aforementioned issues should be carefully considered before making a purchase.
