Sure thing. Strip the frame to a lightweight aluminum or carbon tube, ditch any non‑essential brackets or mounts. Use a compact 3‑gear cassette, keep the chain short, replace the full‑sized fork with a lightweight carbon one. Drop the brakes to rim if you’re racing, or a simple disc set if you need a bit of braking. Keep the battery in a small, high‑density pack and cut the wiring to the bare minimum. That’s the route. If you want more power, focus on torque‑efficient gearing and a minimal tire width. No fluff.
