Solar Panels for E-Bikes
BP Solarex Mega-LiteModules
Are durable, light weight and versatile. Will survive road vibration. No glass is used in theirconstruction, simply EVA laminates and stainless steel backing. Less than half an inch thick with 10-foot two-conductor output cable attached. Five year limited warranty, 90% output.  Use one panel for 12-Volt DC bike; use two panels in series for 24V.

E-Bikes: Solar-Assisted or All-Solar?
A solar-assisted bicycle is an ordinary bike or electric bike that has a solar panel added, to extend its range. A very small solar panel, such as 2Watts, is appropriate for just keeping the bike's battery charged. A larger panel, such as a 20-Watt unit, will provide significant power, to add to to the energy stored in a rechargeable battery. This will extend the cruising range. A solar-converted e-bike  does not qualify as a a real solar bike. It will usually be heavier than a  racing bike. And weight is everything in all-solar competition. An all-solar racing bike requires at least 100Watts of solar power. So, an all-solar racer will have solar panels mounted front, rear, and sometimes on the sides of the vehicle frame, to get that amount of power (solar rallye pictures).
Converting an E-bike to Solar Assist
Unless you are a solar racing enthusiast, the easiest way to build a solar bike is to convert an existing electric bicycle . Just add one or two of theBP Mega-Lite Solar panels to the front or back. Mount the solar panel over the front or rear wheel. Use a pivoting mount so that you can pivot the array to face the sun on long straightaways. Most of the ride it is easiest toleave the panel horizontal. Connect solar to the bike battery via a diode or switch, to prevent discharge of the battery into the solar panel, at night. A charging regulator, such as model PR/SC-12/4, is required if the bike will be left in the sun long enough to overcharge the 12V battery. The charging regulator (or controller) will stop charging when the battery voltage reaches 14.2V.
Converting a Standard Bicycle or Scooter to Solar Assist
One can modify a standard bicyle by using a ready-made kit. See the kits made by Heinzmann (best), Currie, and Bikit. You do not need a bike shop to do the conversion.
Bargin-Priced Solar Bike: If one owns a bike shop or has access to machine tools and has metalworking experience, then almost any bike, scooter, moped, or small motorcycle can be converted to solar. Throw away that blown engine and replace it with an electric motor! It is not easy. For the smallest vehicle, you can use a 12V DC motor. Larger bikes use 24VDC and 36VDC. For a serious cruising bike, an ac motor and ac speed controller/inverter would be ideal. Most racing e-bikes use DC motors that are operated at up to 10 times the rated DC voltage (for a short distance). Motors produce heat. More heat is produced by more current. So the best e-bike design will  try to minimize current  draw during cruise. When designing a solar bike, one goal is to have most of the cruising power come from the solar panel. Starting power would be drawn form the battery. In practice, only 20% to 60% of the required cruising current can be obtained from the solar panel, using conventional construction. But this solar assistance may correspond to a doubling of the cruising range from 5km to 10km, which is very significant if  that is the distance to your job.
Please! Lets put more solar  e-bikes on the road. Endangered creatures of the world need our consideration.
Sealed Batteries for Electric Vehicles - -   Power Sonic
Power Sonic lead-acid batteries are suspended electrolyte, sealed,maintenance-free, leak-proof batteries with high-impact polystyrene cases,usable in any position. They have a 50% capacity retention at 1200 cyclesof 30% depth of discharge, 400 cycles of 50% depth of discharge and 200cycles of 80% depth of discharge. The capacities given below are at 20 hour rate of discharge. The terminals are quick disconnect tabs or nut and bolt,depending on the size of the battery. Height measurements below includeterminal. ISO-9002 certified.
