The Let's Go Aero B02301 is a direct bolt-on expansion accessory for the V-Lectric PRO 3.0 carrier (model B02615, sold separately). It adds two more wheel-mount positions to your existing rack, bringing total capacity to four bikes -- standard, fat-tire, or electric -- without replacing any hardware you already own.
If you're already running the V-Lectric PRO 3.0 (B02615) and need to haul a third and fourth bike, this add-on is the purpose-built solution. It attaches directly to the existing carrier structure and uses the same modular V-wing arm design, so the expanded rack stores compactly and travels the same way your base unit does.
Each of the two new bike positions uses Let's Go Aero's BlockHead quick-release adjustable wheel cradles. Two sizes of cradles are included in the kit -- one set sized for standard-width tires and one set for fat bikes -- so you're not forced to choose between bike types when loading a mixed group.
Quick-release adjustable cradles in two sizes accommodate both standard and fat-tire bikes without additional adapters.
Each bike position is rated for bicycles up to 60 lbs., covering most standard, fat-tire, and mid-drive e-bikes.
Black powder-coated steel frame with trivalent black anodized hardware resists corrosion through highway miles and weather exposure.
Wing support arms remove quickly for compact storage when the add-on is not in use, keeping your setup tidy in the garage or bay.
The B02301 uses a wheel-mount (non-frame-contact) loading approach. Bikes are secured at the wheels rather than the frame, which protects carbon frames and odd-shaped tubes that traditional cradle racks can scratch or stress. Four cushion pads are included to protect all bike-to-rack contact points.
The system is rated for bicycles with 22-inch wheels or larger and tire widths up to 4 inches, which covers nearly all adult bikes including 26", 27.5", 29", and 700c road wheels. Maximum bike length is 72 inches overall -- sufficient for most full-size adult and e-bike frames.
Let's Go Aero is specific about the limitations of this system. This add-on is not rated for bikes that have been accessorized with baskets, cargo racks, panniers, or other frame-mounted add-ons that extend beyond the bike's standard profile. The weight rating applies to the bike itself, not the bike plus accessories.
The entire V-Lectric PRO 3.0 platform, including this add-on, is RV approved for use on motorized vehicles and tow-behind trailers. The modular wing arm system means you can add or remove the B02301 depending on the trip without tools or permanent modification to the base carrier.
