// How to build Two-Wheeler E-Commerce Marketplace with AI Recommendations
Next.js enables fast SEO-friendly product pages critical for two-wheeler listings, while Node.js/PostgreSQL provides a robust transactional backbone for orders and inventory. Razorpay is the go-to Indian payment gateway for automotive purchases, and OpenAI/Gemini API integration gives AI-powered bike recommendations without building ML from scratch, keeping costs manageable for an early-budget startup.

## Engineering risks to plan for
!Budget mismatch risk: Two-wheeler e-commerce with auth + payments + AI is a complexity-7 build; early-stage budgets under ₹4L may force cutting AI features or using a SaaS template base like Medusa.js to reduce dev time.
!Partial team risk: With an incomplete team, AI and payment integration are the hardest modules — ensure you have a backend dev with prior Razorpay experience or budget for extra time on payment edge cases.
!High-value transaction risk: Two-wheeler purchases range ₹60K–₹2L+, requiring robust payment failure handling, refund workflows, and fraud checks that add hidden complexity.
!AI recommendation quality: Generic OpenAI prompts will produce poor bike recommendations without a structured product dataset — budget time for curating bike specs and preference-mapping logic.
!Regulatory consideration: Selling two-wheelers online may involve dealer license verification, GST invoicing, and RTO transfer documentation — legal compliance scope should be defined before development starts.
