i have seen a reverse trike that you can build in the UK or US at Eco-Exo dot com. The R model is with steering wheel rather than handlebars, which some people prefer. They are based on suzuki burgman components including the original petrol engine power chain. The weight as constructed is 200KG. The desired range and speed for me to use as a city commute is 60mph and 15 miles before an overnight recharge.
I have thought of 3 strategies to reduce weight and electrify the kit and would like your advice on this and any other suggestions:
- use alternative front wheels that are lighter than the stock burgman scooter ones and have smaller section tyres. Use a hub motor (for simplicity) at the rear and a custom designed or adapted burgman swing arm for it.
- same as the first option but using an inboard motor and chain drive to rear wheel.
- 2 hub motors at the front, similar to the original burgman items, with a simple swing arm/wheel and disc at the rear.
Please may I ask you to comment on each option and suggest suitable motors, controllers and battery packs. If your advice is to accept lower performance, please suggest what I can reasonably aim for.
The intention is to build to a budget and save on commuting costs over time. The kit costs about £2K.
