I'm looking for a detailed wholesale price quote for several specific tricycle models. It would be great if you could provide pricing information, including any bulk purchase discounts or pricing tiers you might offer. Additionally, please include the minimum order quantities and any available options for customization. Furthermore, I'm interested in understanding the lead times for production and delivery for these models. If there are different variations or specifications available, please outline those as well. Having this information will help me make an informed decision for our procurement needs. Thanks!
