Ride Feel and Handling
The Soltera.2 prioritizes a traditional bicycle feel. Its torque sensor modulates power based on how hard you pedal, producing smooth acceleration and conserving battery on flat terrain. Narrow 650×47C tires make it quick and agile, though bumpier on broken pavement.
The RadCity 5 Plus leans into power and stability. The 750 W motor delivers punchy acceleration, ideal for hauling cargo or conquering hills. Semi-fat 27.5×2.0-inch tires and a front suspension fork absorb road chatter, but the bike feels heavier at low speeds.
Comfort and Fit
- Soltera.2: Available in two frame sizes each for step-over and step-through versions. The swept-back handlebar and 100 mm adjustable stem offer plenty of reach tuning. Without suspension, tire pressure (45–55 PSI) matters for comfort.
- RadCity 5 Plus: Comes in step-through and high-step frames with an inclusive fit range from 4'8" to 6'5". The 50 mm suspension fork and wider saddle suit longer rides, and the bike supports up to 300 lb rider + cargo.
Battery, Range, and Charging
RadCity’s larger 672 Wh battery nearly doubles the capacity of the Soltera.2 pack. Expect 40–55 miles in PAS 2–3 under moderate loads. Aventon’s 345 Wh battery keeps weight low but may require midweek charging if you commute more than 10 miles each way. Both batteries are removable; RadCity uses a semi-integrated downtube pack, while Soltera.2’s sits externally on the downtube.
Maintenance and Service
Aventon’s mechanical discs are easy for home mechanics to adjust, though they need more frequent tuning. RadCity’s hydraulic system provides stronger stopping power and less hand fatigue but benefits from annual bleeding. Both brands supply spare parts online and maintain growing service networks; Rad Power offers mobile service vans in many US metros, while Aventon partners with independent bike shops.
Technology and App Experience
- Aventon app: Bluetooth unlocks Class 3 mode, tracks rides, and controls integrated turn signals. The full-color display shows battery percentage.
- Rad Power app: Offers ride logging, remote diagnostics, and firmware updates. The RadCity display is monochrome but easy to read in sunlight.
Which Bike Should You Choose?
Pick the Aventon Soltera.2 if you value:
- Lighter weight for apartment stairs or transit.
- Lower upfront cost with room to accessorize later.
- Natural pedaling feel from the torque sensor and responsive cadence.
- Quick city rides under 15 miles round-trip.
Pick the RadCity 5 Plus if you need:
- Extra power for hills, cargo, or towing kid trailers.
- Hydraulic brakes and suspension fork comfort out of the box.
- Higher payload capacity and a sturdy rear rack (rated to 59 lb).
- Longer range between charges and optional dual battery setup.
Upgrade Ideas
- Soltera.2: Add fenders, a rear rack, and a suspension seatpost (e.g., Kinekt 2.1) for comfort.
- RadCity 5 Plus: Consider a Thule Yepp child seat, Rad’s front rack, or a battery cover for cold climates.
Bottom Line
The Soltera.2 is a sleek, budget-friendly commuter best for lighter riders and flat-to-rolling routes. The RadCity 5 Plus is heavier but far more capable for hauling and hills. Factor in terrain, storage, and how much cargo you plan to carry before deciding. Either bike can become a car-replacement workhorse with the right accessories.
