Received 2 bikes of the 750LF. One had the crank and chain guard messed up with overspray of the insulation foam from factory for packing. Tried several solvents without much success in getting it off. Finally tried acetone and it did dissolve the foam but also took out the paint from the crank and dissolved the plastic chain guard. Another issue was that my bikes came with non suspension seats. The picture in their website shows it having suspension seats. It is also stated in the operator's manual having the suspension seat. I contacted Rattan regarding these issues and they responded within 2-3 days. They told me that they have contacted the factory and will send replacements for both components. In all fairness, both these issues were not their fault but the factory's. Thank you, Rattan support team for your prompt response to my queries.
