Hi there! Finally I got the control arm mounted! Now, I am thinking about what is next? I can ask the authorities to allow me to registrate the bike as a motorbike, even though the front wheel is a MTB wheel, or build a pedal sidecar and power the chopper with a electric bicycle kit, that...

Hi Elektrosherpa! One option to make this street legal, would be to add a sidecar with pedals and a bicycle hub engine on the chopper frame that only works when there is someone pedalling on the sidecar. I would also like to add a small trailer; if the vehicle is a bicycle it is a much more...

Hi Flippy! It is a great idea to get a second hand electric motorbike with papers, and take the electric engine and instal it as a kit on a donor bike frame that I like! I am waiting for a reply from the certification lab to see what are the requirements for an engine/controller/battery for a...

Hi all! I have been studying how to make an electric conversion street legal in Spain. Every EU country has different regulations; and some are more friendly than others like Germany or the UK. However it seems that in the near future the rules will be standard for all EU countries and...

There is the Crystalyte hub motor I found through a french dealer: https://ozo-electric.com/en/rear-wheel-hub-motor-kits/10788-thru-axle-motor-kit-for-mtb-12x142mm-and-12x148mm.html The kit costs 769E.

Hi Cephalotus! I have many interesting routes in mind in where to get lost with my next project in Spain or Catalonia! The logistical problems of the travel can be considered minor issues, compared with the titanic task of finishing the prototype I am working on. I am looking forward to add...

Sorry for the delay on the my replay! Thanks for sharing your project AF7JA, it is very helpful to learn from the previous experience of others! It is good to know that a solar panel suffices to provide the energy required to charge the batteries if touring at low speeds. On the other hand a...

Parajared Sorry if I my explanations were vague. To put a bit of context I build a couple of recumbent tricycles intended for urban commuting but had some nasty experiences with cars, despite riding in the bicycle lanes. This prompted me to build a sort of recumbent buggy in were the rider is...

Thanks MadRhino and craneplaneguy for your inputs! In were I live most of the year we enjoy sunny days, the idea is to have the battery located flat on the roof, acting as a canopy to shield the rider/s from the sun. However in case the battery gets discharged the rider/s has to be able to...

Thanks flattire for your comments, Although I understand a solar panel has many limitations as the only source to charge the batteries, I think it is a concept worth experimenting. For the time being I am not interested in achieving high speeds. However since it is just a protoype if the...

Hi there! I am a recumbent bicycle builder enthusiast. After having build several tricycle protoypes I am considering trying an hybrid electric solar pedal set up. The option of installing an electric solar panel to charge the batteries, to avoid having to depend on the electrical grid, seems...
