stay away from...
- Motors built into the 5 or 6 spoke magnesium or other alloy rim. You wont be able to replace the motor without buying it in an whole new rim. These rims can get bent and aren't truable. These are very stiff riding.
- Folding ebikes that are priced less than $1000. You simply cannot build a quality ebike with good components for under that price.
-Batteries inside frame tubes- these are very specialized, and will be very hard to replace. And expensive since they are very limited quantity in their builds. Also if the BMS fails it likely will be hard to access, and of a unique shape to fit inside the tube.
- Kickstarter or Indiegogo ebikes. While the ebikes might be priced attractively initially, these are not companies that have thought through a well designed distribution plan, and they usually cannot build any sort of dealership quickly enough to keep their business models from failing. What they might offer in terms of design novelty, they will seriously lack in follow through support and service, bc they are operating on a shoe strong budget, that can't possibly be funded properly via a crowdfunding business model. The jury is still out big time, on how any of these crowdfunded companies are doing, and whether they survive beyond 3 to 5 years. Virtually anyone can start an ebike 'company' and contract with these dime a dozen chinese factories, and white label anything they want. Manufacturing is essentially dead here in the US except for all but the most expensive of products, and further there is literally no supply chain here for everything from the motors, to brakes, to cables, to frames, to seats, to rims, and its all overseas, primarily in China. To deal with China and make products there successfully you have to have US people on the ground there. You cant do it via occasional visits, or emails or telecom, and expect any sort of success. Companies like Apple can do that, but starting up any company, let alone an ebike company, takes VERY deep pockets, that wont come from crowdfunding. I'll give you one example of a firm that is struggling mightily, called Geo-Orbital, who had one of the most successfully crowdfunding campaigns in history. The reliability issues they are having and total lack of a field support structure, is costing them a lot of money. Their design is very complex. And its just for a motor in a wheel. And they are trying to do it 'locally'. Tough row to hoe.
