Serfas is an ebike brand sold in bike shops. They have a variety of models and several are less than $2k. Some models are also 'step through' making it far easier to climb aboard. Their Dash 350 is a very nice model with a 350 watt motor that tops at 20mph and is not expensive.
They are also easier to gets parts for compared to internet only brands. They are also of far higher quality than internet only brands.
They are sold in the shop where I work and we've never had a problem or complaint with any we've sold.
